    Home Made Carb Stand

    I have the same problem with my 82. I also advanced the timing which helped a little. The shop manual describes a test to check the spark advancer by bringing engine speed to 6,000 rpm or above and using a timing light to check that the index mark is between the full advance marks. If it's not...
