long story, but i just bought a 72 johnson 20hp short shaft. it runs and starts easy. issue is the low idle. i have the motor running pretty well, but, its only out about a 1/4 - 1/2 turn. any more and it dies due to over rich settings. plugs are pretty wet so i know its running rich. when i took apart the carb, it had a new float and looks like it was rebuilt. i took out all the plugs and blew them out, and reset the float level, installed new seat and float valve.
i have spark (1 new coil)
110/110 psi, cleaned and rebuilt carb with omc parts.
a fuel pump that i pulled from a running motor.
new hoses, including the crankcase hoses.
here are some photos. the bearing doesnt fit (?) . i can see way down the body that there seems to be a collar that would accept a sleeve (bearing) but what is the stupid part number??? i ordered the part number listed but as you can see there is no way this is gonna fit.
dont know if this shows the carb body
when i pulled the needle this morning, i noticed it was only a 1/4 turn out. all of the other jonnyrude carbs i have worked on the 1 1/2 turn was always pretty close.
arrrggghhhh
