I don’t have any service history on this Craigslist motor. Didn’t idle to bad when I got it but was hard to start.
Since I’ve had it I did the water pump ,carb rebuild, ignition tune up minus the coil(I have a new one if needed)
I will try the flywheel fore aft movement today. I don’t see any oil on top of the block near this bushing/bearing .
It runs way better after resetting the points and carb sync. A boat test to get the carb needles set right is what’s needed.
Question: the omc repair manual says first adjust high speed needle to highest and best speed. I lean it out from the initial 3/4 turns ,and it really races. I don’t want to lean it out too far. Do I go for highest rpm ? Will it be too lean if I go for top RPM? Then go to set the low needle for a good idle. Manual states then go back and reset the high speed needle. Need advice here.boat trip today. Thanks, Jim
