Subject: Re: 79 Spitting fire-backfiring-more specs
The carburetor is a Weber down draft. It hasn't been taken off the
stands yet, so I don't know how it runs as I am cruising. The symptoms
are:
1) runs slightly rough.
2) as I rev. the car, it "spits" out of the carburetor (noticeably in rhythm).
3) I don't think it "spits" on deceleration.
4) Timing is at 10 degrees BTDC @ 800 RMP w/o vacuum advance.
5) It holds a high RPM with no problem, it is having a hard time getting
there.
6) The mixture screw has been moved to both extremes with no
success (so far).
7) I want my little car fixed (whine!)

Generically speaking, dealing strictly with fuel supply, when a carb
backfires out the intake, the car is running too lean--exhaust backfires
come from over-richness. You didn't specify if your running a DCOE or
DGAV. Does the backfiring go away after the car warms up? Does it
only backfire when you accelerate, cruising at a level speed, or at idle.
How about some specifics?
