Hi, first post, I’ve had a search here but haven’t been able to find info I’m after.
I’ve a dumper with a 3cyl, air cooled engine (TR3 ?).
Starts fine from cold but if stopped when hot it won’t restart. If it get a jolt when at idle that causes the revs to drop (clutch out too fast or tip heavy load suddenly) the engine cuts out and refuses to restart.
Sometimes if I play around with the stopper lever at the pump it may restart. If stopper lever is not 100% against its stop it will not start hot or cold. I get the feeling that some adjustments around the stopper lever (or govener) aren’t helping my cause. There is no more external adjustment left on the mechanism.
Battery is fine, starter is fine, fuel flow seems fine (transparent filter housing in fuel line from tank).
Starts fine from cold, runs fine all day.

Any ideas what’s causing my problem ?
