UPDATE Got er done except for the missing bowl gasket, secondary accelerator pump diaphram and accelerator pump diaphram check valve. All missing from a new verified correct unopened Mr. Gasket kit. 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.
