OK, I'm baffled. My 1985 BF100 starts easily, pees strong, revs up quickly and easily in Neutral. However, in Forward or Reverse there is no power. Won't rev up. It acts like it's running at half throttle but it's wide open...???

The wiring seems intact. The magnetic switch at the shifting toggle seems to work (ie: continuity in N, but not it F or R with wires disconnected from motor and connected to my meter...am assuming this is correct).

Wondering if it's carb? electrical? gas w/ ethanol? thoughts?
