Ok, found the carb breather hole was plugged. Also the main needle is sticking now...it was dirty at the points where it contacted the main jet. I tried to clean and polish with a copper brush. Wasn't very effective. Still not running correctly. Low end power is good, but the top end is notchy and I still cant rev from 7k to 10.5k without a stall or bog.
Does anyone know where I can get a #37b needle for the original Keihin carb??
