The plugs look pretty good, and I'm not going to monkey with it anymore. One thing that gave me fits is that the choke plungers weren't going all the way back down when I lifted the choke levers so it would run real rich, wouldn't idle, and dribble gas out the carbs (so I fiddled with the floats). Once I figured this out it tuned up nicely. Every time i lift the choke levers I also push the plungers down with my finger. I also gave them a little shot of WD40.
You here too?
