Holley Jet Extensions
Another problem that will cause a stumble or hesitation is when the secondary jets become uncovered, and no amount ofaccelerator pump tuning will cure it. This occurs when a car leaves so hard that G-force loading on the fuel in the secondarybowl causes it to be pushed up against the rear wall, uncovering the jets. BG Fuel Systems Stainless Steel Jet Extensions willcorrect this situation. Whenever jet extensions are installed in a carburetor equipped with a secondary power valve, the power valve must be removed and the hole plugged. Jet size must then be increased accordingly.
