    What have you done to your square lately??

    When you get to work, run the motor until the oil heats up completely. Short, short trips are murder on motors. Anyone want some sludge??

    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.

    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.

    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?
