Rebuild Carb Pt2 (lars)
Here are some pics of my carb, there ones one more pic that it wont let me upload but its on the back side and it has A-N with a punch like marks? I'm sure lars or someone can explain what it is to me but here is the best description I can give,
A . . .
B . . .
C . .
D
E
F
G
H
K .
L . .
M . .
N
The periods being the punch marks, i didn't get to look into the choke this weekend. Should I replace the choke system and then go from there? I tried reading one of lars threads about rebuilding q-jets and thats way over my head. How much would a rebuild cost if I were to send it to lars? Or just in general?

I have 3 17057204 carburetors for my 1977, one of them is the original.
2 of them are Rochesters including the original.
Both the Rochesters have the punch marks.
The Carter built carburetor has the lettering but no punch marks.
Build dates between 0417 & 0847 with the original being 0677
To me, something seems askew about the photos of the Carburetor you posted.
