I have looked at the other post regarding this engine and I have a similar (but different) issue with this engine. It's a Rover fitted with the Suzuki 2 stroke motor. It starts first time every time but surges at low revs but running fast seems ok. I have stripped and blown out carby with air hose, fuel mix screw (undamaged) has been set to one a half turns out, made all new carby/manifold gaskets from automotive gasket paper (oil and fuel proof) and sprayed with the solvent based spray before assembling again. Adjusted the governor as per a post I saw on this forum, checked engine crankcase seals (all ok), new spark plug, no bent linkages or springs and no links are binding or rubbing on anything to restrict movement, all governor springs are in ok condition and fitted properly as per the photos of same setup I've seen on one of your forums. The only other thing is that I've used a piece of foam from Clark Rubber as a filter element as the mower was not fitted with one originally, but have soaked in 2 stroke oil and then squeezed out excess as one would need to do. As I said starts and runs on fast really well but surges when down to idle, I have also tried as an alternative solution making the gaskets from the bottom muffler gasket material from A Victa 18 muffler system as I thought a bit more body would give a bit more seal when tightened, so I have tried 2 different options for the gaskets. The only thing I can say is when it is running on fast when you put it on choke slightly it starts to die (as one would expect). I'm running out of ideas so I need new light shed on this. Any suggestions sincerely appreciated. Cheers all and thanks. Mike
