    When I had the Holley off the engine and flipped over on my workbench, I noticed that there is about 3/16" play on the secondaries between closed and sitting on the adjustment. I was trying to set the transfer slots. I set it so when they were open, there is only about .020" reveal on the...

    I do not see fuel dribbling down the Venturi clusters at idle. The ignition timing and the firing order is confirmed and correct. I will do a compression test this evening. I used the Holley trick kit that Holley technical support sent me.

    VP 4.3GS Carb Tuning Vacuum Port?

    I will take a picture of it when I get back to the house. I'm 99% sure I figured out what my fouled plugs problem was. The primary float was adjusted so badly that I don't think it could ever shut off. I've had about 2 inches of gas and oil mixed in my oil pan above the full mark. Also...

    I have not even fired the engine since I rebuilt the carb. I want to make sure I have all of the initial settings correct before I start the engine and tune it properly.
