OK guys, who is really up on the Holleys?
Q #1. Accelerator nozzle check ball/pin.
On a 4165 series carb, (spread bore DP) what type of nozzle check is used. The little balls, or the pointed pins? I'm rebuilding one, and it had neither. The primary pump reservoir has the orange/pinkish umbrella type check valve below the bowl to prevent pushing fuel back into the bowl when the pump works. But nothing under the nozzle screws to keep the fuel "charge" up in the circuit at the nozzle....I had some check balls from kits over the years, but the .058/.062, (1/16th inch) ball just falls through. I would think the pointed pin was used on these models, but neither pri, or sec had anything under the screws. Am I to assume these parts were left out by the previous owner? Also, the secondary bowl has the old style ball check in the reservoir.....
Q#2. I have the same missing part on two 660 center squirters. There was nothing under the center nozzle of either carb.....(EDIT, OK I looked at the other 660, and it DOES have a pointed pin thingy under the nozzle, so disregard the 660 question...)
I know without those check balls/pins, the accelerator pump circuit drains back and causes either a "pop" or a stumble when you nail it.....So, which type was used in the 4165 series, and the list 4224 C/squirt carbs......Ray
PS: The "blow up" of the 4165 supplied with the kit shows nothing under the nozzle screws???
