Biohazard
Put the thicker carb gasket on and, right away, the choke valve landed right where it should.
Started the car up and backed her out of the garage under her own steam. It was glorious!
She'll sit there and idle till the tanks empty but wants to stall if I try to give it any gas once the engine is fully warmed up. Is the choke butterfly supposed to be completely vertical when the engine is fully warm or should there still be some pitch?
