Title: Dial in 17059217
Post by: F250 Restorer on October 21, 2022, 03:59:18 PM

I'm trying to bring this carb back to its original specs. To my surprise, I find the main air bleeds in the main body are at .110, and the air bleeds in the airhorn are the same. Shouldn't those be at about .070?
Idle air bleed=.066
Idle down restriction=.045
Idle bypass=1 @.066, 1 @ .070

I haven't pulled the idle tubes yet, but what should they be?
Thank for the help.

The MAB's, both pairs should be closer to .118/.120".

What are the upper and lower IAB's measuring?

What jets and rods are in it.

Idle tubes?

DCR's?

What are you trying to use it on?
