Checked the coil with an ohm meter. Showed to be within specs, 1.5 ohms from + to - post & around 9500 between - and hole in middle of coil.

No I haven’t checked the filter. Forgot it had one. If it ever stops raining I’ll check that today. I did rebuild the carb about 2 years ago so I’m assuming it’s not the trouble. But with today’s fuels I could be wrong.
