got the plugs, plug wires, distro cap, ignition rotor all changed out sea foamed the gas and intake manifold and finally checked the timing........ after i let it idle for about 15 mins, i set the idle to the recommended 600, and my timing is lining up with the middle mark of the 3 at about 6 degrees!.....10 off from the 16 (+/- 2). but the distro was already adjusted all the way advanced/counter clockwise. will sliding the timing belt off the cam and turning it to the left or right 1 tooth fix this? if so, to retard it from that side which way would i need to adjust the teeth?
