17057231 specs?
Cadman-iac:
Does anyone have the specs on this carb, specifically the idle bypass size and the mixture screw hole size?
If you have the idle tube size and the secondary bleed tube sizes, I would really appreciate those too.
Many thanks in advance, Rick
GSP7:
I have a 1980 , 17080213 that I had measured the Idle Bypass Air holes in base plate , .108".
If that helps.
Cadman-iac:
I appreciate your input but this is a 1977 Cadillac 425 carb and I think the calibration might be a bit different than yours. Hopefully someone will have the information I need. Thanks for your effort though.
Cliff Ruggles:
What are you trying to do with it? Stock application or something else?
All of the later Caddy units are pretty close for calibration and used small MAB's and large CFM castings.
They make excellent HP carburetors, just need a little help in a few areas.
I have every single part available for them including the most complete/correct rebuild kits in this industry.......
Kenth:
Here are the specs for 1977-8-9 Cad M4 230 units. Like Cliff says, similar all years.
