🔧 4M Quadrajet Rebuild Kit for JET 201004 Review

The parts included in the kit are of high quality. The instructions were a bad copy of a bad copy. Very difficult to read. The kit did not include a tool to measure the height of the float. I was lucky enough to have an old restore kit that included a tool and also a gasket that was not included in that kit. The seals that came with it were of good quality.

I'm sure Jet knows the problem because the accelerator pump cup is blue in my Jet carburetor. This kit is a way to ditch bad inventory and turn a profit. GOOD SEAL.

I have a 1975 Corvette and the ad says kit #201004 should fit. Guess what? The kit is designed for Quadjets from 1966 to 1974. I called Jet Tech Support and the guy said I needed the #201003 kit for later naturally aspirated carburetors. Because Amazon uses the same batch of detail images, it's impossible to tell which goes where. I found a better kit on quadrajet.com that has crisp custom content images for less money; The carburettor number is 17055038, so correct for the car. I don't have a…
