I ran the O.S. powered .91 Seaducer today for the first time. Everything went well. Bob came over and helped; he lives in Canandaigua too. I noticed the throttle arm on the carb came loose on the last run. I was wondering why the throttle was changing on me at times. The water was perfect, like glass, and the rain held off for me. I put about 4 or 5 tanks through it. I'm running 40% nitro now, an X462, and a 12.5" pipe length. I think I'll try a X465 and a shorter pipe before I go any leaner. Any suggestions??
