hello,

When my engine is cold, a single qick start the engine.
after an hour or two the engine stop and does not restart for a while.
Then start again when cold.
Do you have any idea on my ignition problem?

BR, Jacques

I doubt the original poster will check back, but the problem sounds very much like a failing magneto coil. When heated, the winding becomes segmented, breaks in the wire. The result is very little energy when trying to kick when warm. Additionally, you should make sure that the magneto has been timing correctly. It might have slipped from alignment.
