Reply To: RD-17 bottom plug fouling – no high speed power

[The red boat]

thank for everyone’s help on this subject.
Other than swapping out the high-speed needle for a better one and replacing the spark plugs, I did nothing else to the motor other than some disassembly of the carb and re-assembly.
re-confirmed the cam timing, etc.

I took the boat out on the water this weekend and everything is in good order.
After I fine-tuned the hi and lo speed needles I got to enjoy an afternoon of boating and fishing!
Once the motor cooled down enough to touch i pulled both spark plugs and they looked great. dry; nice tan insulator and no fouling.

when revving in neutral, the vacuum cut-out worked as it should and i had no other problems.
whatever gremlin had take up residence the week before has apparently moved on.

thanks again!
great site!
