After my last post, I had some success. After screwing around with the choke, idle air screw, and drying the plugs, I got fed up and left it alone for a few hours. Went back out, pumped the gas twice, and it fired right up. It ran for about two minutes, but it wouldn't idle, and revving the gas had no affect.

I spent some time looking at the carb, and found one issue. I had forgotten to put the plug back over the low speed jet. After finding that issue, I decided to tear the carb back down and fully inspect it. I found the a Carter service manual, used the appropriate pages, and went at it. The only other issue that I found was that the choke linkage appears to be far from the recommended factory specification. Put everything back together, and manually operating the choke and throttle, still could not get it to fire.

I would've thought a single barrel downdraft carb was pretty simple, but it appears to be winning. I'm going to put new plugs in tomorrow (the one item in the ignition that's not new) and then try it again. If that doesn't pan out, I may just send the carb to a pro so I know it is right.

Incidentally, where does one connect the heat riser tube for the thermostatic choke? Should I just run a steel or copper line and butt it against the exhaust manifold?
