Thanks again……..

You are 180 degrees out of time. Pull the dist and turn the rotor directly away from where it is now and it should fire right up. You are currently firing as the air/fuel mix is going in.

X2 on it being out of sync 180 degrees.

Here's how to correct it:

With everything as is (distributor being installed 180 degrees out, engine backfire, etc):

Disconnect the battery
Turn the crank so that the timing mark on the balancer reads "TDC" and the distributor is pointing at the #1 plug.

THIS position is actually 180 degrees out of sync. NOW, turn the crank ONE REVOLUTION to "TDC" again.

VERY IMPORTANT: ONLY TURN IT ONCE!!!!

Now you will observe that the distributor is NOT pointing to the #1 plug at all. This is good. (at the moment.)

Next, PULL the distributor out and re-insert it so that it is pointing at the #1 plug.

Snug the distributor hold-down bolt a bit, but not too tight that you can't turn the distributor a little bit. (for timing it later).

Re-connect the battery. Hook up your timing light. Fire it up and time it as you would normally (engine at operating temp, distributor advance removed and vacuum line plugged).

Don't worry. I've had this happen to me, too, and I had to have someone remind me that there are two "top dead centers".

Hanging my head in shame......

Yup, I was so rattled that I didn't bother to check if #1 was on the compression stroke. Obviously it wasn't. Got the beast running and timed. Had it idling for half an hour with ac on and so far it's still going. Sure hope this is the end of this hassle. If so I learned a lot. If not......back to the drawing board.

This board has some very helpful chaps, and threads like this remind me of how great a community this is to be a part of.

Thanks for everything

Got the beast back up and running. Took it for a long drive today with no problems. Guess the sensor in the distributor was the problem all along. I am now a much wiser dude. Thanks for everything guys.
