Title: working on Olds 7043251 Main body air bleed question
Post by: Mr.Pontiac on February 12, 2016, 03:34:13 PM

I notied on this carb. the main body air bleeds are very small .038 and your book calls for .070. the jets in the carb. where .070,s and idle down are perfect at .046. So should i go ahead and open it up to .070????

If it helps idle air bleeds are at .070 perfect accord. with your book.

The MAB's are typically small in the Olds quadrajets.  smaller DCR and larger idle tubes.
Are you building it for stock spec Olds or for something else?

I would leave them alone and stick close to the factory calibration for an Olds application.....Cliff
