Hello all!
I have been palyin with a 406 this summer.
My question is when I accelerate and I shift from 1st to 2nd and 2nd to 3rd I get this surge like miss but if i put my foot in it alil more it goes away is this a sign of lean condition or rich.
it is a mech. secondary 750 mighty demon carb other than that the plugs are a lil browner than i like but they are burning alright.
My timing is set at 20 deg. base 34 total vacuum advance not hooked up it runs thew best at these settings
