No, the cover is original. The gentleman that owns it owns seven self-propelled push mowers. He is a little eccentric, I have been servicing and maintaining them for years. I believe the problem is in the flywheel magnet. I have a source for a used flywheel, however the shop that it is at is...

That sounds interesting, I will try to find my old compass and give it a try. Sounds like a good way to measure comparative magnetic strength.

Yes, the only visible difference that I can see are the cooling fins. I have a couple of locked up Briggs engines, tomorrow I will check the flywheels and try replacing the one on the problem engine.

Yes, both are original.

The diameter is the same, but the cooling fins are much taller and pronounce on the Poulan vs the Murray and would not allow for the top cover to be refitted. Besides, the customer is picking up the Murray soon.

No, however, on visual inspection the flywheel and crank slots are exactly lined up, and the key is in place.

120k02-0418-e-1 on the Murray 22 in walk behind trimmer I just happened to be rebuilding (and was waiting on parts for) when I started working on 123k-0217-e1 the Poulan Pro lawn mower (problem machine). Both the original coil on the Poulan, and the new coil, are the same. Both failed to...

No, they share some common parts, but the flywheels are different.

Yes, I just read up on it. It is located within the coil itself. This could not be my problem due to the fact of the coil not working properly on the problem machine, yet working just fine on another. My guess right now is it has to be the flywheel. Somehow it is capable of sending enough...

Interesting. Where is the Darlington transistor located? Could this be the cause of intermittent spark?

No, the machine which worked perfect was working on the parts (coil and plug) which tested bad on the above machine. When tried on this machine, it had no spark and of course would not start. Something is causing the coil to miss-fire. I ran down the ground kill switch, tested the ground wire...

Correct.
