Air/ fuel tuning

back on my tune.
have got most going very good.
idle:13.5
off idle:14
cruise:13.5
sounds really crisp and goes good .

only thing is the slightest opening of the throttle starts the pump shot, and brings it down to low 11 , maybe a 10.

pink cam #1 28nozzle. primary.
seems to want the instant fuel , but obviously not so much.

im gonna try a 25nozzle next.
the pink cam seems to have the slowest ramp.

ive tried several cams and #2 positions but i get a hesitation.??

is there a common choice for a decent cam motor , have 5" vacuum up to 11" at light cruise
