|
|
I have a 1967 Beetle. Currently running a AK 1600cc Single Port engine. I have a 30 Pict-1 75-1 Base installed. The correct carburetor for my car is a 20 Pict -1 with a 105-1 Bade (with the power circuit)
I am having a few small issues with my current carb and looking into replace it.
My question is, should I spend the extra for a 105-1 base with the power circuit, or is it worth it? Anyone use one, notice any differences...etc? Thank you! |

The 30-1 carb I have has a 75 base but it has the power circuit on top. I think there's a way to modify the 75 base so it works properly with the power circuit _________________ '66 Beetle

The 30 PICT 1 tops are interchangeable. If you are running an 009 or some other mechanical only distributor I don't think you'll notice any difference. Iff you are running a vacuum advance distributor you will need to match it to your carburetor. _________________ Roads Scholar &

Yes, I've said it many times, the bases should be already set up for the power fuel system. All it needs is a clear channel as shown here:

I am running a 009.
Big question... can anyone tell me if they ever tested any difference between running a engine with the 75-1 and running an engine with the 105-1 power circuit?
I don't notice any problems with my Bug getting uphills right now, but supposedly others have told me the 105-1 is the carb I need. |

Uh, yes, I have experienced it when the power fuel system got bunged up and it certainly led to a lower amount of wide open throttle power.
And that reflects a service book note that VW made during the 28PICT-1 era regarding a certain series of carburetors that might have issues:

Does anyone have a picture of the upper half with the power jet circuit? I’m trying to find out if my upper half has it. My base is the vw 105-1. Thanks. _________________ 69' Westy

Is there a performance difference between 105's, 75's and 78's? I figure the numbers reflect what vehicles they were put in? I have all three and each has a power circuit so is there really a difference? Want to keep the best performer for my 67.
I've noticed that the power circuit tops have an arm that screws into the top to mount the return spring on (and the top has a corresponding mounting point). |
