guage should be checked off of a intake runner port if possible . if you have nothing hooked up to the front PCV port on the carburetor , you need to do so ASAP so as to help your relieve crankcase of all the oil vapors in engine caused by the crankshaft rotation. this will cause poor engine running as well as major oil leaks . Also , is all this cam and etc all new . Are you sure your not overcammed ? Sounds like you may be lean as well , do to a vacuum leak or a carburetor problem .

All new parts in engine. The machine shop sold me the cam and said I wouldn't need to run a stall convertor but I'm not sure it doesn't need a small stall. Hopefully tomorrow after work I'll have time to try some of these suggestions. I'm ready to ride and not be a snail off the line.

All converters are "stall" converters. The question is how high the stall speed is.

My guess is that you have too much cam. Drill a 1/8" hole in each primary throttle blade and then turn the idle speed screw back a bit. Set you idel at about 700 to 750 and THEN adjust your mixture screws. After you get the idle mixture set, THEN reset the speed where it is most comfortable for you.

Would a higher stall converter help get off the line quicker? Right now it's really slow off the line. I have a turbo 400 trans, 3.73 rear gear and 29" tires. I thought the 305 would have enough power to push my 55 Chevy truck but it just doesn't have the get up and go I thought it would. Maybe after the carb gets tuned it will get better.

You really should get all the cam specs before getting a converter. BUT, that being said, there's never anything wrong with swappin in a 3000 rpm converter........unless your cam needs more.

Likely, yes. A looser converter allows the motor to rev past the sluggish low end part of the cam's operating range and apply some real torque to the tires.
