TR thanks for the in depth info. Once I can get it to start I'll do exactly that.

Currently it won't run at a normal idle. If I set the curb idle very high it will stumble and 'run' with black exhaust (still haven't gotten exhaust done past the header). I've tried adjusting the idle mixture screws with no discernable effect.

It seems to be dumping too much fuel into the intake at idle, even with the idle mixture screws set 1/4 turn open.

I rebuilt the carb (new gaskets, power valve, accelerator pump) while the engine was in pieces. Broke off one of the mounting fingers on the base plate when mounting and then found a 7448 carb on ebay and used the base plate from that carb with the upper from my original.

More description to follow.
