"Blue cam on 30cc or put 50cc pump on it"

^^^^^this

We never had any hesitation issues on either the 750 or later the 850DP carbs we ran on my 340 car. However in an effort to make things even better with what we had we put a 50cc pump on the 850 and noticed a good improvement even on the street when testing, it had the desired effect at the track on the hit f/braking, and that carb was almost 2/10ths quicker in the 1/4 than the 750DP the car came with so a good gain for not a lot of money, just glad I used to think out of the box as everyone else at the time said that was too big of a carb for a small motor.
