They are fairly simple engines. Start with the basic ignition tuneup and go from there.

Coil, or coil wire. The coil wire works 8 times as hard as the rest of them. Its all a guess from here

I had the same problem. Fuel pump was going bad Ethanol ate it up. Ran fine at idle and up but when secondary's opened up it would cough and die. Pump pressure went to 2 on the gauge from 7
