I took the carb off again and had it blown out at a friends who has a air compressor... drained the gas out of the thank, and took out and looked at the petcock... the upper screen was plugged with a bunch of that looked like dirt, or rust flakes...
put everything back together, and it still runs like crap, and I can only get 20 out of it...
Loosened the exhaust and it makes no diference.
No im really stumped... one mentioned the exhaust port being plugged. the spark plug is clean, so what could be plugging up the exhaust port? soot from the burning oil?
Oh well... I might try a new plug anyway, but after that.... it might make a good boat anchor...
