I can't get this pony motor to rev up or run right. it will idle ok but that's it. gone thought the mag, and carb, gaped the plugs. I am not running it with that air cleaner on it. I have change the timing 3-or 4 teeth 20-30 degrees nothing changes much. it has good compression cat roll it over TDC by hand.

did it run fine before? Salvage workshop on here had an issue with the gear driving the Mag on his track loader. have you looked further into the intake horn so see if anything got sucked up in there? she's pretty rich. What about trying to run it with the fuel turned off and just using starting fluid to try to narrow it down

Weak spark? Sounds like it is misfiring a lot.

Not the coil, condenser or points... internal mag short maybe or bad. mag switch?, ... had one where the points spring was bent in such a way it wouldn't close all the way ...gave me fits .... recently had some points I had to relay scratch them up to get them to work ????? still got me on that one... First thing I thought of was magnets skipping in the flywheel but wrong type of mag but that's what it sounded like.... Coil is shorting some how here, carbon tracers. Turn off most of the lights and see if you can see spark jumping.... You say you replaced the coil? on IH mags you have to be careful not to scratch up the ends of the iron core segments when reinstalling - clean all contacts with rubbing alcohol . check cap for cracks and carbon tracers all copper plug n coil wires. You watch it will be something easy.
