Hi all, I thought I would share my story on these great little Suzuki 2 strokes. About a year ago I scored my first mower for free, at that time I had no real idea about them or what they were like, the guy that gave it to me just said he couldn't get it run and he had the carby off of it so first thing I checked was the spark and there was none so i asked a relative that is a small engine mechanic what he knew about them and he told me to remove the coil and give it a clean with some sand paper as they get rust and corrosion between the mating faces on the block and coil and this affects the earth continuity, so I did that and reset the coil air gap. This fixed my no spark problem which was great so I start it up and it runs ok. The first few times I use it, it seem to go through a lot of fuel (a tank full in about 20 minutes of running time) so I asked my relative to look at it for me and he said they do use a bit of fuel but after telling him how much he checked it out for me, as soon as he looks at the carby he starts laughing because the guy that took the carby off in the first place had swapped the linkages around so the throttle was acting as the choke and choke as the throttle so it was basically flooding itself yet it seemed to run ok and still had plenty of power. The engine itself did have a bit of a bearing noise and was hard to start when it was hot but it ran fine and the more I ran it the better it got ( just a quick tip on 2 stroke fuel as a lot of people seems to make this mistake is don't over oil them as this causes an excess of carbon build up in the engine and muffler and causes them to be very sluggish, I have found using Opti 2 stroke 100:1 oil with BP ultimate 98 fuel cleans the engine and muffler out, you would be amazed at how clean the muffler on mine is compared to when I first got it). So anyway I picked up a second mower cheap that wouldn't start either, this one had spark but you could smell stale fuel and it was flooded so I took it home and stripped down the carby to find a stuck needle that gummed up in the open position and the guy I got of left the fuel tank on so the piston was swimming in fuel, After cleaning the carby and taking the coil off to clean the mating surfaces I got it going and it went great except it would hunt really badly with no load on it, so I went to my local mower shop and the guy pulls out a box of Suzuki parts that were just random pieces he had there and to my luck there was a brand new governor spring in there (unlucky he only had 1) so I put the new spring on and it solved the hunting problem and it was going great except for it was a pain to start when it got hot as the other 1 did so I decided it was time for new bearings and seals in both engines so i went and got the parts I needed and stripped them down and I could not believe how simple they were to rebuild (it does help when you have a press,lathe and the right tools on hand) so this fixed my hot starting problem because the seals were now doing there job as the old ones were quite badly worn but doing there job well enough to start and run but when they got hot they would allow just enough air to bypass to make it too lean to start hot. The first motor I rebuilt had already had some dodgey work done to the flywheel previously so when I put it back on it started to split through the taper as I tightened it so I asked my relative if he could get me another flywheel, well he brought me another complete mower and said i could strip it down as the guy he got it off only wanted the base back so I thought i would see what was wrong with the engine, first thing I did was pull the starter to see if it had compression which it did then not checking the throttle to see if it was actually in the off position i pulled it over again and it started on me but it was very rough when it ran so I went through the carby and cleaned the exhaust out and restarted it but it still wouldn't rev very well so on this one I was a bit rough and gave it a few good hard revs pulling back on the governor linkage and it blew a ton of smoke out and seemed to clear it out a bit but was still hunting really badly so then I cut and rebent the governor spring for more tension as these seem to get weak with age and this sorted out that problem and it to now runs great. So hopefully if you have read this long story you may have gotten some new tips on Rover Suzuki 2 stroke engines, Thanks For reading Cheers Steve
