A compression test is the cheapest and easiest thing to do to find out

flywheel key, coil, ignition module, and as simple as a bad plug wire
or plug that fails to carry full current under load but will idle, ive
had all these things happen. Was any gas left in the carburator over
the winter, empting the tank doesnt empty the carb, if gas was left
in, then the carb is what I would do first.

If it starts and runs, if only for a minute, the timing is ok. Timing
doesn't change under normal circumstances. Spark plugs can operate
under a "no Load" condition, and fail under a load. He obviously has
an air/fuel mixture problem.

He said it fails under throttle, to me that means many things that it
could be, but the most logical is he left gas in the carb.-

That would be my first place to look too. As I stated, an air-to-fuel
ratio problem, which is usually caused by a dirty carb, or some
restricted fuel flow problem. But, we'll probably never know.

Well I reset the spark plug gap, rocker arm clearances, cleaned and
re-oiled the air filter - so now it idles fantastic. Unfortunately it
still stalls on full throttle.

I plan on pulling off the carb next. The spark plug was covered in
carbon so its probably a fuel mixture problem.
