Zenith Stromberg 150 CD3 Carb rebuild

Pulled the carb off. It’s a zenith Stromberg 150 CD3. Did it once Saturday to adjust the mixure. Took several hours. Not much of a change occurred in how it ran.

So I pulled it off again, only took 35 minutes the second time. Really helped knowing what I’m doing. Opened it up, and had a look, it at least needs a new metering needle. So I’m sending it off for a complete rebuild and cleaning. I don’t think it ever was rebuilt. If for nothing else it should look better.
