At my wits end with this QuadraJet

[1bad79]

The holes are where the air comes from and how it bypasses the throttle plate I just bought this carb it’s a 73 olds 750 cfm auto carb and has factory bypass air not
all have it

I’m a hoarder of books

If I was you ied buy this book it’s a great resource I also want to buy the Doug roe book just to have it

I was just re reading this I may have pointed at the wrong holes I’ll check on it

 

[1bad79]

Ok I guess I was right

That is a lot of compression and cam for a carb that came off a 8 to 1 350? with a 180's duration cam, Either pick up Cliff Ruggles book, mine was ruined in the 2013 flood or I would send it or contact Techg8.

I hate giving any advice on carb problems because there are so many variables. To answer your question you can be on the primary circuit, the throttle blades should show no more than .040 of the transfer slot in the closed position. Your idle screws should be 1 and a 1/2 turns out

I was gonna say, 3-3 1/2 turns seems like a lot. I always run mine 1.5-2.5 max.

I run mine in the 2-2.5 range and I think my holes under the screws are .090 and my bypas holes are like .110 and idle restrictions are .036
