Its still not right . About to give up but found this just now

I took mine apart to clean the varnish out of the carburetor. Re-assembled and installed. Would not rev off of idle. Struggled with the main jet, thinking that was the issue. NOT. Found it to be the brass sleeve that surrounds the main needle (slide needle). The brass sleeve was not lined up correctly. It MUST be lined up with a small pin at the bottom of the casting. Once I got that lined up correctly, runs great! Fuel was not being pulled through the main jet since the fuel port on the slide-sleeve was improperly aligned.

Not sure what part of sleeve needs to be aligned with pin but will check later
This sounds promising - previous owners may have pulled this sleeve out . I pulled it out but wasn't aware of alignment requirement .
