Re: 1981 Evinrude 9.9hp 2str starts but won't run
Forgot to ask, did the motor ever run properly? If so,was there any work done on it afterwards? Assuming you have good spark and it is timed properly you might try another tank, and fuel line from tank to motor. You could also try gravity feed directly to the carb through a separate line. If none of that works it may very well be the carb which could be re-cleaned and blown out with compressed air. Or you could just gamble on a new one? As mentioned above if the plug is dry after the initially firing it is likely starving for fuel. My guess is that if the motor sat for a long time without having the carb drained the carb was/is pluggrd up?
