Suzuki 2 Stroke Mower Manual
Toro/Suzuki engine start question. Anyone else experience that problem with their 2-cycle mowers? I have had residential lawnboys older ones two stroke with. We have parts, diagrams, accessories and repair advice to make your tool. Toro 22040 (89999)(1998) Lawn Mower Parts. In Stock, 2 Available.
Hi Bampter, and welcome to Outdoorking. The usual cause of hunting is lean mixture, as you obviously know, since you have been focusing on the fuel supply. Incidentally I hope you cleaned and inspected the fuel filter. However there is another, less common cause: friction in the governor mechanism, caused by, for example, a bent link which jams slightly, something rubbing against a lever, or a pivot that needs to be lubricated.
I suggest you look at the governor mechanism to check that it moves freely, but lean mixture remains the more likely problem. You should be able to verify this though, by restricting the intake air slightly when the engine is hunting, to see whether that clears it up. Most (not all) engines, including yours, have a choke which can be closed a very small amount to make this test. If your engine had only a primer, not a choke, for cold starting you could either obstruct the air filter's intake passage, or remove the air filter and obstruct the carburetor air intake.
I do not recommend running engines with the air filter removed, especially if they are running lean, because they may 'spit' burning fuel from the air intake, and this is hazardous. Here is the workshop manual for your engine: There is a likely cause for lean mixture other than the fuel system: an intake air leak, on the suction (i.e. Engine) side of the carburetor. This usually happens in one of two ways: the gasket between carburetor and engine is loose or damaged; or air is leaking directly into the crankcase, perhaps through one or both of the crankshaft seals. In most cases if these are leaking there will be oil around them. Please try closing the choke slightly to establish definitely whether the problem is lean mixture. If it is, investigate the items I have listed.
Either way, let us know what you find, and we can continue the diagnostic process if necessary. Re: SUZUKI M120X 2-STROKE HUNTING 18/10/12 08:45 PM 18/10/12 08:45 PM. Hi All, Hope someone can help me. I removed the carb off my Suzuki M120X Rover lawn mower and I cant seem to get it assembled correctly. I have read the service manual but it does not show how to correctly install the linkage arms. Also not sure if both butterflies in the carb must be closed when trying to start the mower.
The mower used to run but was VERY sensitive to the throttle position, then it stopped running completely. There is a strong spark from the plug but I am sure it has something to do with the carb. Any help would be appreciated. Re: SUZUKI M120X 2-STROKE HUNTING 19/10/12 05:01 PM 19/10/12 05:01 PM. The seals would have to be pretty bad for it not to start.
A victa with a warped head or dud decomp will still sometimes start provided it not a huge huge leak, If it is they usually pop smoke and flames out the offending orifice. With the plates in the carb. The furtherest one in is the throttle plate, full noise is full open. The outer one is the choke, full open is choke off, closed is choke on.
They both have their own function. To break it down. Carbs start with the fuel in the bowl. As the air goes through the carb due to careful differences in the size of the bore etc in the carb it makes different pressures and the air sucks fuel out of the bowl through jets up into the air stream. There is also an air passage into the fuel bowl before the throttle plate, so in the fuel bowl is a higher pressure than after the throttle plate. Its the same deal as how an aeroplane wing works but inside a tunnel with a bowl under it.
Then the air and fuel ratio needs to be right. Thats done with the jetting in the carb. The first thing that affects jetting is the fuel level or float height.
This needs to be right. Its all working on pressure differences.
Liquids do not compress, air being a gas does. The throttle butterfly controls how much air can flow through and that controls the engine speed. So the first thing you need to be sure of if you have had the carb appart is that the fuel/float height is correct. On a two stroke if you have the oil in the fuel ratio way wrong that effects jetting too.
Its burning fuel to run. It burns oil as a by product of how its designed. If you have too much oil you do not have enough fuel. If you have not enough oil you have too much fuel. Not as important with a mower as it is with a high performance bike but it is still relavant.
Given what you just said in the post above. Whats the story with the plug?
Id suggest you try two new ones. Some plugs look good making spark outside the motor. Stick them in a wet damp hole at 6 or more times atmosphere and they dont want to play the game. Ive had new plugs out of the box that dont work. Ones that look good out but dont work aer usually those cheapie mower shop/part brand type ones and some champion, im not a fan of champion plugs. To be sure its getting fuel and work out if its lean or rich on the fuel, get a teaspoon of fuel and put it in the plughole. See if it kicks.
Try it with the plug you have. Repeat with a new plug. If you keep an eye out you will find a whole mower for parts for a good price. By that I mean under $50. They do command a bit of a premium. Its taken me a while to collect enough motors etc that I will have enough bits. What I would dearly like if anyone has it is a PDF or link to an online Parts list for the motor.
I have a mate that works at a Suzuki bike shop and he said if I can give the part number he should be able to get me bits. Re: SUZUKI M120X 2-STROKE HUNTING 21/10/12 05:58 AM 21/10/12 05:58 AM. Yes Bob, When I think about it, I have had a power torque engine running, looking through a gap in the head gasket at the flame inside the cylinder. I even went & grabbed the misus to show her that one, she just though I was crazy. Suzuki has no head gasket. But the seals are on the other side of the piston, so as the piston moves forward there should be high pressure in combustion chamber & a vacuum in the crankcase to draw in fuel.
This would have to affect starting. I dont have a parts list, just one I have made up over time. Try the Torro web site in the US, they have a manual but no part no.
Also try the australian site 'spare parts online' they have suzuki bits. Thanks for posting the photos. My rover xl with the Suzuki 2 stroke had a little hiccup yesterday. After pulling the carby apart and cleaning I reassembled the beast. It follows the picture that was posted. I have an issue though. Muscular system labeling study guide answer key. The engine starts fine but I have no throttle control other than applying some choke.
The throttle plate is wide open. There does not appear to be any resistance on the governor lever to return the throttle plate to closed position.
The outcome is that the motor starts and then runs absolutely flat out. The kill switch still works though. The question therefore is how is the appropriate resistance applied to ensure the throttle plate returns to closed position. Or maybe I am completely off track.
Happy to be educated. Re: SUZUKI M120X 2-STROKE HUNTING 22/10/12 07:52 PM 22/10/12 07:52 PM. Hello, I have 2 of these here that I still have to look. One takes 4 pulls to start. The other is hard to tune. They can be difficult to get right.
I would check your governor set up again. When you reassemmbled it was the governor shaft all the way to right, then place the governor arm on the shaft so that it is all the way to the right, please see image below. I have had your problem before. I re-adjusted the governor arm on the shaft slightly. Check it all moves as it should with your finger. Also are the carby gaskets sealing and not sucking air. This manual is available from TORO's website.
I have bought a Rover mower with a 2 stroke suzuki engine. I think I'll keep it if I can get it going. I have had the mower going briefly so I know it will run. The problem is that the previous owner has had a go at the carburetor linkages and I dont think all the parts are there. In particular the spacers that are shown in this photo are missing. I have jury rigged it with some dodgy spacers but they aren't the right fitting. Does anybody know if the spacers can be bought?
I can't find them in the parts listing online but they might be in a kit. Here is a shot of the carburetor (mobile phone quality I'm afraid) I'll clean up the mower when I'm finished.trust me, I will. Membership information Re: Rover Suzuki 2 stroke 17/01/13 06:37 AM 17/01/13 06:37 AM.
Hi Joe, It was the carburetor adjustment. Without the correct spacers the throttle cable wasn't able to push things properly as the bolt held everything too tightly. I replaced my bodgy spacers with a piece of copper pipe and the result was better. The choke closes now for starting but it's still all very stiff. I think the throttle cable will bend if I leave it like that. I'll have to keep an eye out for the proper spacers, washers etc but I haven't seen many suzukis up here in Mackay.
This one was brought here by a new resident to the town. Re: Rover Suzuki 2 stroke 20/01/13 01:44 PM 20/01/13 01:44 PM. Not normally one to dig-up an old thread but I've nearly done with a complete Resto/Refurb of a SUZUKI 2T Rover deluxe. This is a GREAT Mower.
I'm normally a Victa 'Full Crank' and at a push a Powertorque guy but this is a really nice bit of kit. This was a great unit in it's day with super revs and a 4 Blade plate. I am told it was a favoured unit by councils etc. I got mine to run with the squirt-can prime but would die immediately. It was in tidy, complete but neglected condition. Carby rebuild was clean and no real issues that several different gauges of wire an xtra small drills and pin vices couldn't fix.
Carby fixed then you have to redo all the tensions of the cable to control. Anyone who's done a Honda, Chonda, Briggs will work it out soon enough. I got it going OK then stripped it down to do a proper Resto/Refurb (slow weekend) I needed to to get the throttle sorted but it ran like a trooper and had a good note as well so an engine pull-down was not needed. Getting the governor-Throttle- choke raltionship is thi tricky bit but once sorted, we move on to see if it's worth anything.
Just a lot of degreaser, scouring pads and petrol. The unit was covered in dust-oil sediment so I thought to strip the components and do a basic refurbishment. Not just a tune and flip. It was a unique bit of kit with all the ROVER deluxe bits, a 4 blade carrier, Alloy chassis (in great nic),chrome hubcaps, good catcher.

It's faults were minimal. One dodgy wheel ( ) the Carby was a mess so a full pulldown with some dilligent application of Cat5 wire and engine winding coils wire I had the Carby to the point where I had 'some' throttle control shutdown. Good start so I then redid the carb settings and clean and flushed so I was confidant I'd have a fair runner and I got it to run almost decently. One wheel bearing was shot, as was the cather flap sping.

I won't lose sleep finding those bits (in fact I stripped them from another Rover 'Deluxe' with a suspecected broken piston ring, waiting in queue for it's judgement). This DeLuxe was too good for the bin. A bit of tweaking the throttle input mech and she's a pearler. A FULL pull down and clean. Then some well applied epoxy.
We'll have a super good. The Rover deluxe Suzuki 2 stroke which will soon be in a place of honour next to my collection of 20-30 other unique mowers. And worthy addition to my personal collection of hundreds of 'Things that Spin'. A Unique bit of kit that does it's job VERY well. As good a mower as my Honda but with 2T grunt and my own handbuilt detail. I'll be proud to park it next to my Mustangs, Super-24's and Tricked out Utilities. I have a balanced and tuned Utility with a Tuned Mikuni that spins to over 7000rpm and you can hold on to it.
I'll limit it to a bit less when I put blades on it though. BTW Every 'collectible' mower I own mows my font lawn at least once a year. (it does get a GOOD clean after) but it gets a run. Hi brycevr, Thanks for the post. Been looking at this and other similar threads recently as my Dad has a Rover XL from the early 90's with a Suzuki 2-stroke. My Dad no longer mows, but it's a quality piece of kit as it was subject to at least 10-15yrs of Sydney mowing and shows little external wear apart from the wheels. My Dad said it was becoming difficult to start- 3 pulls, so based on what you and others say I'll look at the choke adjustment then carby esp.
As the fuel was allowed to dry out in it- hopefully carby cleaner will be enough. Posts like yours pointing out particular problem areas and fixes are very helpful. I am a great fan of the Suzuki M120X & a great deal of them were sold here in New Zealand on Rover bodies.

I see one of the above post talks about one of these being hard to start. A contractor some years ago told me a trick for cold starting these engines.
Stand the mower on it nose for about 5 seconds (Spark plug facing downwards)I guess some fuel spills out the main jet & primes the engine, usually first pull the engine starts. I have noticed some of the American Toro's fitted with this engine actually have a carburetor primer bulb fitted, but none do in the part of the world. Hope this helps someone.
