First thing... since it was towed... make sure your engine isn't full of water. Spark plugs out, and crank.


Anyway... Sounds like you are doing the right things... but.....

1) Verify compression.
2) Verify the rotary valve timing.
3) Verify fuel system. (make sure you can suck fuel to the carb hose) If there is a leak, it will draw air.
4) Verify the carb. Build it to "Book" specs, and make sure to use ONLY OEM Mikuni parts. The aftermarket kits SUCK !!! They cause more Issues than they solve.
