Rochester 1BBL main metering jet an air bleeds

[Geri]

Hello Pick´upper

Can someone tell me something about the main metering jet´s and the air bleeds from the Rochester 1BBL Carburetor from my Inline 6 235?

I have two of the Carburetors at home. One of them has a .58 jet and the other an .71 jet. Wich one should i use or should i buy another one for my 235?!?

Other question is about the air bleeds. They are also different. From the carburetor with the .71 main jets they are bigger than the other ones.
Can i change the bleeds or is it permanently tuned?

Thanks a lot good luck in the soccer world champion chip :-)
