There are two possibilities for a vacuum leak, external and internal. With the motor idling, use a propane torch (not lit) and play the gas around the base of the carb and the intake manifold where it bolts to the heads. If the idle speed goes up, there is your external vacuum leak. You can't find an internal vacuum leak with gas. It's where the bottom of the intake manifold ports are open to the crankcase because the intake manifold ports and the cylinder head ports are not parallel and the motor draws in oily vapors when the intake valve is open. Have you checked the plugs for oily?
hope I dont need a converter.
I did readjust the valves and it got much better but still not there
Here is the cam specs :288°/292° 224°/224° .450"/.460" 114°
32 degrees at 2000 but I also have the vacum advance where Holley says to hook it up ....but there is vacum there all the time even at idle.
How close are Holleys from the box.....could it be to rick or lean?
