440 tuning troubles

The car wouldn't even start with the AFB on it. I don't have any explanation for that.....
So I went back to my original 750. I changed the acc pump cam, readjusted the pump arm, and tied the choke open (I think it may have been contributing to the problem).
Now when I stomp on it in first gear from a rolling start, there is no stumble or pop through the carb...only radial tire screaming for mercy as it gets lit up!:cheers:
Thank you guys for taking the time to help!=D>=D>
