After 2 months of rough as hell cold starts spitting and sputtering playing with the timing making sure the dizzy is in correct. I finally remembered about vacuum advance. The only thing is I'm not sure this darn thing has it. There's no canister no lines running to the dizzy. So, did a 87 GT have vacuum advance. If so where'd it go and how does one fix this.

Thanks again

 

Is it the stock motor? If so the computer controls the advance.

 

as said above the computer controls the amount of advance, also remember you must pull the spout connector to adjust base timing or youll never get it right.
