Hi All

The problem of the engine stalling when the clutch is pushed in is an intriguing one. First a question what happens if you screw the idle speed stop screw in so that the engine is held at high idle right at the carb? Does the engine stall when the clutch is pushed in?

If it doesn't - then here is a thought, the engine mounts, all of the bolts, and even the holes in the frame wear. (See picture) the pushing in the clutch can move the entire engine transmission just a little bit. If the engines idle speed is not controlled by the set screw at the carb but instead by one of the others adjustments over riding it this can be a problem.

If the engine stalls even with the idle set to high when the clutch is pushed then try checking the really dumb things that could never be the problem like the grounding of the engine to the frame add a clip lead.

Bobs suggestions are a good check list, take a look at each of the suggestions and give us the results if you would, we all love a mystery.

Cheers Phil
