Also, isn't moving the chain two teeth around the big part of the idler sprocket the same as moving the "dizzy" one tooth over Cause I couldn't get it to work like that either. I don't want to get back in there if that isn't what it is. The distributer is turned all the way counter-clockwise to get 18 degrees at about 1100 rpm.

I also found a vacuum hose that was off. So I put it back in and it started running better, but it is still not running right. And the distributer didn't line up when I put it on I lined it up to the number one cylinder. That is the way that it was when I couldn't get it to rev at all, So I set it one more tooth before. Now it starts right up and runs, but it idles like crap. I can't really keep it running for very long, cause my heater core exploded, or something. It is draining into my cabin. Oh! Also, I have to have my distributer set all the way to the right, meaning that the actual distributer is turned counter-clockwise all the way. It seems to be dead on the 18 degrees BTDC. It will be easier when I can get it to idle right. Also, the idle adjustment screw isn't seeming to do anything. It doesn't raise the idle, or lower it. It seems to do absolutely nothing.
