I have one of these Tecumseh carbs that has the long pointy low-speed needle that interfaces with the long pin inside that slides up and down. The one where you have to be sure to insert the screw with the carb upright as not to jam that pin up.
I have one where that internal pin is gummed up. I freed it up a bit but not completely. Any tips on how to get that to rattle again?
Thanks.
