I purchased a carburetor from guaranteed carburetors 10 years ago and could never get it to work properly. I sent mine in for the core which was a very bad mistake. The carburetor they sent me was from a 1984 gmc truck.
When I disassembled it recently the rich mixture stop screw was screwed in all the way and frozen up. I could never turn it to adjust.

I purchased a 1981 carburetor 17081228 1321 FOX several years ago. Now I am rebuilding it to install on the Vette. IMG_20210131_141954.jpgIMG_20210212_214101.jpg

I have a couple of questions. 1-The manual says not to install the choke gasket because of grounding issues. I've used it with a gasket in the past with no issues. 2- Does anyone use the plastic insert that installs below the m/c solenoid?

I have another Carburetor 17081228 1321 FOX that I am going to be rebuilding also.
The 1984 GMC Carb on the Vette, will be for sale minus the choke pull off and the a/c idle solenoid.

I've never had to do any carb work on ours yet. Seems like the choke would be grounded through the screws.

Leave the gasket off for electric choke. If stovepipe (hot air) you need to put the gasket in for it to work properly. Always put back in any shields in carburetor. GM spent a lot of money and people who a lot smarter than us to develop and design those parts.
