No biggee..
First of all make sure you have the accelerator pump adjusted properly..
Heres how to do it.

Engine OFF, push the throttle linkage all the way.
Adjust the accelerator pump arm to have a slight clearance such 0.050s..
Now try it.
If it still bogs slightly try another position on the plastic accelerator cam. Recheck the accelerator pump arm clearance clearance again.
Now try it.
If it still bogs, bump up the squirters 1 step.

Holleys are super EZ to tune, be patient and take your time it will run fine..

Just my
