Capt. I think what he is trying to say is...he is trying to put the distributor in correctly, not necessarily "timing it". Is this correct 79c? If so, here's a start. Put your finger/little ball of paper towel in the #1 spark plug, bump the starter over until it (finger/towel) pops out, stop! Turn by hand (same direction) until the line on the balancer lines up with 8*before top center. Find the #1 spark plug wire on your cap, draw a line on the distributor base straight down from the center. Now you need to put the rotor on this mark when it's fully seated against the intake. This may take several attempts to get this right. If you can't get it to drop in on the line, you will need to use a long screwdriver to turn the oil pump driveshaft a little. The vacuum can needs to be pointed in a way so you have room to swing it each way to get exact timing set. Once you have it this far, put a timing light on it & set it on about 8* BTC. Any additional help needed, just ask, Lorne
