I’m new to any automotive work but have wanted an older American vehicle for some time now. My strongest pull has been towards 60-66 Chevy and GMC and pulled the trigger on one this August.
Mostly original 3/4 wide standard bed GMC. Base model w factory power brake. Was parked in a neighborhood I pass through w a for sale sign in the window.
It runs pretty good as is but is running real rich. Need to tune the carburetor and I’m looking for advice. First I’m looking for what model Holley carb someone installed, carb has numbers on it but I think they’re serial numbers
