Hello,
I just bought a couple of skis. The mid 80's 550 runs well until it wants to foul the plug on one cylinder. Rather than play the tuning/rebuild/tune again game with this thing I would rather just replace the carb, tune it, and be good to go.
I imagine the carb has been rebuilt a handfull of times given its age, and each person probably stuck wires in all the passages, etc.
So which carb is a direct replacement for the stocker? As a motorcycle performance shop I have access to new Mikuni super BN carbs in the 34, 36, 44, 46mm range. The watercraft is all stock except for a pipe.
I want to get this thing reliable so we can ride it without messing with it. Compression is 145psi per cylinder.
Thanks for your help guys,
Jon
