Choke not closing on rebuilt quadrajet
I believe GM, back in the day, had a drainage problem with some new cars, so they came up with a fuel filter with a flapper valve to prevent fuel from draining out of the carburetor.- 73c20jim

8 MPG?
I was told by a friend of mine who used to be a mechanic in a Buick dealership back in the 60's, that when a customer complained about poor gas mileage, they would change the speedometer gear to make it look like better mileage. Works for me.- 73c20jim

Choke not closing on rebuilt quadrajet
Could the carburetor be draining back towards the fuel pump, so it has to be filled before it can start???- 73c20jim

Coolant for C20 w/ 350
Diluted coolant is a ripoff. Buy 2 @ $8.88 = 17.76. In those two you get a total of 1 gallon of concentrated anti-freeze. 1 gallon of concentrate costs $10.87. Therefore you are buying a gallon of water for $17.76 - 10.87 = $6.89. Want some waterfront property in Arizona?- 73c20jim

The reason I did little work on the truck is, I got 3 Cowboy guns. two Rugers and an Armi San Marco, from the actors in town that needed fixing. These guys always come first. "Grumpy" Jim, armorer of the stars. P.S. Any conversation on this, add to...
