Carter or Rochester?

Hi Cliff,

The lower idle airbleeds are .067.

Also, the idle tubes are larger, I pulled one out and it was .039.

The stock idle set up would be good enough for me, unless you have a better idea.

The Rochester of the same carb number that I bought has .039 idle tubes, .052 DCR's, and .067 lower air bleeds, .092 upper idle air bleeds. I don't know if it is the stock setup.

I await your opinion..

Thanks,
Greg Carter

I didn't understand your reply about the 76/44 jet/needle combo you sent me until today.
You said they were specified for the original mabs of .118.
Since my carb has smaller mabs, should I take them out?

Thanks ahead,
Greg Carter

Cliff Ruggles:
Yes, use the 76/44 with the stock size MAB's.....
