if your carb sucks like mine has for the last three years take it to John at C&J. I had the best weekend of boating ever at the CP regatta thanks to tweaking he did on my 3 circuit Dominator. No more bogging, no more misfires at part throttle, the thing just works killer now and I'm stoked on it. The boat drives like its got a 4150 on it.
this is total spam i know, but this guy is the man and I wanted to pass on the good vibe.
