Re: lhart-us

When it stops, do you still have spark? Does the carb still pump fuel from the accelerator pump holes?

Is the engine carbed or EFI? Serial number of the engine would help.

Don't worry about what part is causing no spark until you find out if missing spark is the problems. The module doesn't normally come and go after 500ft.
