Re: Need engine timing basics
Here's the sure fire method for cranking her up for the first time.
1) Rotate the crank by hand until the harmonic timing indicator is dialed in at 6-8 degrees advanced. Make sure the compression stroke was just complete (or more accurately, "almost" completed). If you're not sure, you'll have to pull the driver's side valve cover and watch for the closing of the number one intake valve.
2) Pull the number one plug wire off the spark plug. Then install an old (but working) spark plug in the number one wire boot.
3) Make sure your rotor in the distributor is pointed toward the number one plug wire, or at least close.
4) Loosen the distributor tie down bolt
5) Turn the ignition key to the 'on' position.
6) Ground the old spark plug to engine somewhere,..away from the carb (obviously)
7) Rotate the distributor back and forth in your other hand while you look for a spark from the grounded spark plug. You're trying to pass the number one terminal on the distributor cap past the rotor tip to locate it's positon.
8) Position and maintain the distributor in the position where the spark is achieved
9) Turn the ignition key to 'off' (it shouldn't stay in the 'on' position for longer than a minute, but this method takes about 20 seconds).
10) Tighten the distributor tie down bolt and re-attach the number one plug wire to the plug.
Assuming the fuel supply is good to go, she'll fire right up,.. which is good for engine break-in.
