Thanks Mel,

Upon looking carefully at the carburetor, I think something is missing.

I talked to my dad and at one time this carb was overhauled by a fellow who started working on it, then suddenly passed away. Someone else reassembled the carb.

As I'm looking at it, there appears to be a main nozzle missing. I found on yesterday's tractors a ford N carburetor rebuild page and that tractor uses a zenith carb too. Clearly, I'm missing the main nozzle.

So, does anyone have one or know where I could purchase one? It's the piece that threads in just downstream of the main jet and extends to the middle of the intake chamber just below the brass venturi.

Thanks everyone for viewing and hopefully helping me resolve this problem.
