1992 Johnson J10RENA--what's the main jet diameter supposed to be?
I bought this motor used and I'm wondering if the previous owner tried to "modify" the 9.9 carb to a 15 by changing the main jet. The motor runs good at idle up to ~1/3 throttle and then starts to run rich.
Read my previous post (if you have time for a novel) for the history on this motor. Sorry for the ramblings. My fuel pump was OK . . . the nozzle well wasn't properly seated and I had the idle jet waaaay too far out. Now it runs, but has the symptoms I described above.
