My turn to ask for help with a Holley.

TrailBeast said
A friend is fairly busy and has two carbs that are acting up and he asked if I could help.
The one in question is a Holley 9379 750 double pumper competition carb with four corner idle jets.

It's been forever since I rebuilt a Holley, and I thought I would ask if there are any special things to look out for.

Thank you.

Be sure to get the newer non-stick gaskets. Watch a lot of the on-line videos about rebuilding, adjusting and tuning Holley carbs.

Pay close attention to the position of the throttle blades in relation to the idle transfer slots.

Install a wideband A/F gauge to help tune the air/fuel ratios across the board.
