You have wires going to the carb on a 72 Chevy c10?
There were no 1998 Chevy Celebrities made.
get a chiltons repair manual from the library for 67 chevy's.
What carb? what diagram for what? did you just smoke a big bowl?
It is important to have a diagram of the part of the car that is being changed. A vacuum line diagram for a Chevy Scottsdale will be found in the maintenance manual, found at auto part stores.
Use a dwell meter to set the gap at 30 degrees.
Check for vacuum leaks. It sounds like the carb may need to be adjusted.
there is no carb on that truck
1989 Celebrities are fuel injected, there is no carb.
when you buy a rebuild kit for it it should have instructions, very simple carb to rebuild.
1982-1993 Chevrolet&GMC S10&S15 pick-ups (Hayens Repair Manual).
