Well, I got the carb on and hooked up the choke, fired it up and just did a 20 min drive with no problem. The car still "diesels" a little though when I turn it off (it slowly shuts off over 2 or 3 seconds). So, it needs a little work. But, I don't hear any pinging or knocking. The choke opens as it should. I did notice that the exhaust popping doesn't really happen until the choke is all the way out. So, it could be a mixture thing. It's definitely not as bad as before, though. It's going to my shop on Tuesday for some minor things. But, I was driving it today... now it is raining! crap...
