20 hp Merc again!

[JOHN12]

Got 1980 20 hp merc *561----- running after switch box/charging coil replace and carb rebuild and to the lake the last two days,

ProbleM: Running at 1/4 throttle it misses pretty bad and at 1/2 throttle it will run fine then stop as if I pulled the kill switch, but then restarts on first pull.

I did not replace the fuel pump diaphram as it looked good and did not have one but that may be my problem.

Any thoughts.

Where can I get a "complete full pump and carb rebuid kit??

Thanks

Re: 20 hp Merc again!

you should be able to get the pats here at Iboats.i would rebuild carb probably dirt in jet. when it does it try priming bulb if it starts running ok then you know its fuel pump.
