Had a problem last week getting fire in both cylinders. I changed the plugs, and everything ran good. THIS week, I started it a couple of times, and it ran great. I went home today, and tried to fire it up, and nothing. I mean NOTHING. Can anybody tell me how to test for a bad coil? I can't really afford any expensive fixes right now, so I'd like to try and isolate the problem, and try to fix myself. Problem is that I don't have very much equipment. An ohm meter, and new plug wires, and relatively new plugs. Any suggestions?
