the PO of the car hasnt failed me yet lol so im just trying to see if he has everything hooked up right, my 70 has dual vacuum advance so i cant really compare the two. on the 69 he has the vacuum hose coming out of the vac cannister going to a port under the foward float bowl.
i went to set the initial timing to 10BTDC and then i connected the vaccum hose and looked at the timing and it retarded some. is this supposed to do that? is there a way i can convert to dual advance?
