I've been having some running issues with my ol" hondoo lately. Basicly running rich, backfiring, loss of power, and stalling out. It started mildly and over the last 20-30miles has become undrivable. No codes. Fires right up. Just runs like crap. I flushed the fuel tank. My real concern is this: while its running I pull the plug wire off of the rear cylinder and it kills itself. Pull the plug wire from front cylinder and it keeps running with zero change. I pulled the plugs and both plugs and coils are making an abundance of spark. (That makes me nervous) One plug looks fine and the other looks rich. I have new plugs coming on Monday but untill then I'm concerned about that front cylinder having spark but still not firing. Its not smoking, or blowing oil by and its not making any odd noises.
