Coughing, backfiring ... *UPDATE*

I check the ballast and don't think it's them. I checked timing, and it's good, checked plug wires and replaced cap. I tried switching out ignition controller and nothing. I talked to Don at FBO and he was confident that it's a carb issue and that the carb is flooding out which explains the fouled out plugs and why it reeks of fuel even if I haven't touched the pedal. It also explains why the other night it was flooded when I went to start it, even thought I hadn't touched it. I'm going to clean the float bowls, air bleeders, and replace the needle and seats with bottom feeders. Hopefully with everything cleaned out we'll be back in business.
