Morning: Looking for any thoughts on a MF 35, that was used to pull/clean up a collection of yard vehicles ...
owner shut it off for lunch, and when re-started it needed full choke, full throttle, will not speed up, just a rough idle.
There's no black smoke from the exhaust as if it was flooding, and no blueish smoke either.
He has checked the flow to carb and its constant and a good steady flow as expected, putting a hand over the air intake at the carb, will stop it and the air can be felt sucking in.
I suspect more issue with the carb jets, but have i missed something simple, maybe a condenser/coil failure?
Tks
 
Check the ignition system. More poor running problems are caused by a bad primary ignition circuit then carburetion!.
