Reply To: Johnson FD-12 Won’t Run

[Bob Wight]

Steve D – yes, it has new condensers.    I re-used the original OMC points as they were in good condition.   Just filed and cleaned real good.

Don – haven’t tried it on a boat yet, but I’ve never had one that wouldn’t run smooth in the test barrel.   It seems to idle well, although it did sneeze a few times and it took some adjustment to get it to smooth out.   Idle needle is a little over 1-1/2 turns open, high speed at 1/2 turn.   I’ve looked at the sync adjustments and they seem spot on but I’ll look at that again tomorrow along with the carb and choke linkages.

I’m just puzzled about the big difference in the spark plug appearance.
