Sir Tripower

Hi,

can anyone show me the difference between the Holley #4055 (manual) and the #4056 (automatic)? Both are center-carbs for Tripower-Corvettes (L68).
Does the #4055 work satisfying on an auto-car?

Primary jets 4055, 63 4056, 61.
Primary pump nozzle 4055, .021, 4056, .025
There maybe other differences such as air restrictors.

So one fact is, that I have the wrong primary jets in my 4056. As I found out, there are "63" installed.
As it is rather difficult to get any of those special carb-parts here in Germany, my question goes to you forums-guys, wether anyone can order two correct "61" metering jets for me and send them to me in an envelope? Immideate payment by Paypal guaranteed!

Another question:
After disassemled, re-assembled and re-installed my center-carb for the x-th time, there is no chance to adjust correct idle-speed by the idle-micture-screws. With the screws completly in seat (where engine should almost stall) there is a quite satisfying idle-speed. Turning them out will make idle go down! Seems, that engine gets some fuel from another point. All seals are new (the good blue ones) and correct installed. Has anyone an idea, what could be the reason for that?
