Default finding T.D.C on distributor

i put a new distributor on the car but forgot to see where the rotor was sitting before i switched them...... i take it that 1 full turn to the input shaft is 90 degrees for the rotor......

also, can the shaft go onto the cam at 180 degrees, or is it only 360....

thanks
matt

It can go in correctly, or 180 degrees off. Put the motor at tdc, the rotor facing the #1 contact and you're set.

dont worry, your cool. the notch on the end of the cam is offset so it can only go on 1 way.....

The cam slot is off center. Look at the end of the distributor that goes into the head and make it lines up with the slot in the cam. It can go in 180 out, but you'll have to force it.

make sure the plug wire order to the distributor is correct. I think the rotor can go on 2 ways, try flipping it since u didnt check the old one. maybe the refurbished distributor u got is junk? sometimes the battery dies after cranking on it for too long, make sure its charged. make sure kill switch or anything isn't on. im running out of ideas, good luck.
