The top of the cap will have #1 marked, transfer this location to distributor base with a sharpie. Make sure there is plenty of adjustment of the distributor and that the vacuum canister isn't going to hit anything when setting the timing. Stab the distributor in and get the rotor in the general location of the sharpie mark. If the vac canister is too close to anything, pull and re-stab one tooth either cw or ccw. Loosely clamp down when rotor is at sharpie mark. As long as the engine is tdc at #1 compression, it should fire with minimal adjustment.
