Okay, finally got a rebuild kit for this Zenith carb. I believe it is a Type 67 but I'm not sure. There are no markings and the tag is gone. The float was definitely bad. It was all soldered up. So, the rebuild was much needed I suspect. I also installed a choke cable.
I got it fired up (still with the Carter electric fuel pump on it). Hey! Idles fine. Higher RPM's it is loading up, losing power and blowing occasional black smoke kind of like it was doing that caused me to tackle this project. The warmer it got the worse it got. The spark plugs came out jet black. I'm thinking too much fuel. But there's no main jet adjustment on this thing. The main jet on this carb is #29 below. I don't have the part labeled #27A which is called the Main Jet Adjustment. All I have is the plug which is #27.
Is there a way to adjust the main jet without #27A below? Thanks.
