Well Bax, it's been quite awhile since I posted the problems about my Fuji 50ei. For a short time the acceleration problem was overcome but came back, with a vengence. Same thing. Engine started on 3rd to 5th flip but would not accelerate. I tryed doing it slow, fast & by increasing & decreasing the needle settings for high & low-nothing. Then, after much researching, I thought it might be the high speed jet. It being cloged or stuck would cause this kind of problem. I removed it from the carb (by freezing the carb), removed the litle waffer, cleaned everthing up & reasembled the jet & tested it for one way air flow. All was well. After installation, same problem. I checked air flow travel on the jet againno blockage. I've been trying to figure it out again (past two months) and am compltely stymied. The carb gets fuel, I have a spark & I'm using a spring starter. I thought-maybe old fuel. I put fresh fuel with 50:1 mix to make starting easier. Nothing. Won't even try to start. I checked the other Q & A's on Fuji's. A few problems came close to my experience but non of the solutions did. I'm hoping You've got a good idea on this one, or maybe one of your buddies? Here's hoping-joe
