Re: How do you set a distrubitor correctly?
Keep in mind that the distributor technically can point in any direction so long as the plugs fire at the correct time. The limiting factor is that you only have so much adjustment in the distributor (i.e. the vacuum can will hit the carb or firewall etc.). As a result, the typical installation is to install the distributor with the rotor pointing to cylinder 1 while cylinder 1 is at TDC. (Rotor pointed to 11:00 position as viewed from the perspective of the driver - just left of straight forward) This configuration will make your wires line up and give you the adjustment room you need. You may have to turn the oil pump shaft with a long screwdriver to get it lined up with the tang on the distributor shaft.
