Is it at all possible that the flywheel has lost all or most of it's magnetism?
Unless theres a lot of rust, otherwise I never of a flywheel having that problem.
The flywheel was rusty, I cleaned off the rust and sanded the magnet until it was shiny. How do you test the magnet? It seems plenty strong. When installing the new coil, the magnet held it in place until I got the mounting screws in. I had to pry it loose with a wrench to get the feeler gauge in to set the gap. have to do something. I need that little guy.
I have a Mighty Mac chipper/shredder.. I originally had a 5hp flathead Briggs on it. I wore that engine out so i took the engine off the tiller for the season. It ran so well that I just left it there. Lots of power, never bogged, never used any oil. Always changed the oil at the end of the season. Used M1 5W-30.
I fixed it!! I found 2 specs for the coil to flywheel gap, .006-.010, & .010-.014. At first I had set the gap to .010, right in the middle, right? No spark, later, after R&R the coil several times, I had set it to .008. Left it for a couple of days, today I tried a different sparkplug, still nothing, R&R the coil again, and set the gap to .012. I now have spark. It runs!! Sort of. The carb is badly corroded inside. New carb on order.
Thanks everyone for the help.
