ok I think I MIGHT have figured out the problem. The spring turned inside of the boot and It wasn’t all the way on the spark plug. I think that it ran better at high RPM because the it was putting more juice through the coil and able to jump over. I pulled the boot off, cut a bit of wire off faned out the wires and lubed it up and reinstalled it. and made sure that this time it went all the way on. I’m going to take it later to the river and try it.
