RB Engine "Sticking"
I've got an RB C12 engine that has had approx 2 gallons through it. Over the past half gallon or so, it seemed to be "sticking" when the piston would start reaching the top of the cycle. It has now gotten to the point where I can't start the engine. I was told this was due to the engine gumming up from something in the fuel (Blue Thunder).
So I took the engine apart and have polished the piston and sleeve with Mother's Aluminum Polish, and it removed all of the blue stains on them. But the engine is still "sticking".
When I have the p/s out of the engine and push the piston up the farthest I can push it is about 4.5mm from the top of the sleeve and it sticks.
Anybody have any ideas on what I can do?
Thanks
