Needle and seat look brand new, accelerator pump shot is great.

It is an OEM Chrysler carb, the list number is 4749 or something like that, and it doesnt have externally adjustable floats. I just had a brainfart when posting originally and typed 1850 instead of 4150.

I thought it seemed lean too but it does smell kind of rich. Not smoking much though.

Ill see if gaskets are blocking anything.

Any idea where I can find a rebuild kit for this? Should a typical 4150 rebuild kit have the necessary parts? I cant find the list number on summit to order a kit.
