It has a fitting in it for vacuum wipers or a pipe plug. You can adjust the idle mixture without it. With the engine running at idle speed & warmed up, slowly turn the idle mixture jet in till the engine starts slowing down. Then back it out to the highest RPM, usually 1/2 turn. 5-6 hundred rpm is about right for that engine unless it has an auto matic trans. or a/c.
Georgeeeeeeeeeeee.
They say money can't buy happiness. It can buy old Chevy trucks though. Same thing. 1972 Chevy c10 Cheyenne SuperIn the Gallery Forum | | |
