Heya! Badly need either a cheap 20r carb that you have laying around (for parts) or the specific part:

I need the spring for the primary venturi jet.

if you have a rebuild kit diagram (mine's napa/echlen) it's #56. I either dropped it when I opened my carb up or it was missing from the get go (which might explain why I decided to rebuild it anyway)

any help greatly appreciated.
