Thanks everyone for the replies. I will inspect the pipe to manifold and ma=
nifold to head to see if anything is loose or any leaks apparent in the mor=
ning.
I actually went down a main jet 145 to 140 and that seemed like it helped s=
ome but didn't clear up the issue (which is going leaner; opposite of what =
Greg said).
It is missing and backfiring when I am full on the gas. I can prevent it by=
easing into the gas.
I did notice some gas at my air cleaner to velocity stack connection. I won=
der if it is a float issue?

Subject: Stutter at 4K rpm
Two races ago I went off track and bent my exhaust pipe enough to break the=
welded joint near the muffler. In the interest of time, I cut the exhaust =
at the muffler and secured the pipe to the frame.
At the last race, I noticed the car would backfire at deceleration which I =
am not surprised but I also noticed a stutter around 4-5k rpm.
At NOLA this weekend it is more pronounced and comes in when shifting hard =
from 3rd to 4th. After 5k, it clears up and pulls normally.
It doesn't seem to be affected by turns and more related to full throttle v=
s easing into the gas.
Backpressure from the loss of muffler or unrelated issues?
1300 spitfire with single Weber 40.
