Trouble with rebuild

<< < (3/3)

Cliff Ruggles:
What size are the idle tubes, idle DCR's, and how much idle bypass air?

Different size fuel inlet seats and messing with the power piston and spring are not the answer.  That isn't a very big cam, assuming your 427 has over 10 to 1 compression, it should be relatively smooth idle and not need a ton of fuel from the idle system right to start with......Cliff

Landshark:
I believe the idle tubes are the stock .035, I don't know what the idle DCR's are and no idea about the idle bypass.


I have another question about the attached pictures. Can someone tell me why the difference between these 2 fast idle adjusting plates. The one on the left is P/N 30677 and the other is P/N 35806. I'm curious about why the top tang on the left on is bent and the other is straight.

 What carb numbers are we talking about here? I see you reference 7029201. What is the other carb number? Different carbs used slightly different parts.

 EDIT: 7029201 uses the 35806 (or 7035806) fast idle lever. From my manual, it looks like the 30677 (or 7030677) was used on the B-O-P QuadraJets.
