    Ok folks it looks like it's coming down to bad compression. We hooked up a gauge and the the #1 cylinder is at 75. The rest are at about 45 to 50. My question is now though... what would cause only #1 to be "okay-ish" but the other 5 cylinders to be EQUALLY bd?

    I would appreciate any input and suggestions.

    Thanks.

    EDIT:

    We took the plugs out and put some oil in each cylinder. The compression has come back up on each of the cylinders. Hopefully the rings were just stuck from sitting for 30 years and the oil lubed them up good? I will let you know more when I put the plugs back in and we try to start the car again.

    Thanks.

    Take the dist out, take #1 plug out,get #1 cylinder at top dead center on the compression stroke ,put the dist back in the motor with the rotor pointing at the #1 plug wire position of the dist. after it's seated. The gear is angled so the rotor will move as you set the dist into the motor and you need to anticipate this. The car should start now and you will then be able to adjust the timing.The reason I tell you to do this is that you may be a tooth off in one direction or the other. There is also the possibility the timing chain is jumped a tooth because it's worn out. If it won't run when you have the dist in correctly at #1 the condencer could be weak or shot,the timing chain can th too loose or jumped a tooth.If it's the chain you gotta pull off the front cover .
