I got a yamaha 9.9 1987 model sh and it idles down good but when i run it at full throttle it seems very underpowered. I was thinking about adjusting the carb to see if that will fix it ... any suggestions?
P.S.
bought the motor used from a sketchy outfit so perhaps they tried to adjust it and screwed up the high idle.
thanks
