Zeeb,
Thanks for the suggestions, I DID move the ignition inside and that's when I quite having dead sticks for quite a while. Just all of a sudden without doing any changes, the problem started again. I change the entire fuel system, tank, clunk, lines, filter, everything and still does it. My next thing is either try a new ignition box or rebuilding the carb, but I doubt it's the carb as it runs fine for anywhere from 4 - 7 minutes then just suddenly dies. Usually when the engine overheats, you can hear it sag a little, lose power, then it dies. Mine, just gives a cough, then about 5-10 seconds later dies, almost like it's running out of fuel.

On another note, I got a good look at the B model at the AMA show and talked to Rocco quite a bit. It's really a nice looking model and I'm sure the fans of B models will like it. (Me - I'm a D model type!)
