I recently rebuilt the carb in my 15R75C Johnson. I did like it said in my shop manual to lightly seat the idle jet and back it out 1.5 turns. I then installed the idle screw knob back on with the arrow facing straight down, so I would have room to fine tune. Now I read on a web page that I needed to lean it out in small amounts till the motor either tried to die or heard a mild backfire. Then Rich it and within 1/4 of a turn would be my sweet spot.
lol well the damn thing runs so good after the new fuel pump and carb rebuild that it wont even fart to tell me when to back it out. It runs great on the reset idle placement, so should I just leave it there or am I even doing it right.
