273 running Rich

[1] At operating temp, choke blade should be vertical.
[2] Idle mixtures screws control an air & fuel mixture.
THANKS It seams there is not enough travel in that choke the number on it is 59,I have a new one stamped 67 my idle screws are at 1 1/4 turns out . my manual states rich condition could be wrong gasket at base of carb.or top of manifold. Going to try that new choke. Thanks again.
