Took apart my carb (Gurtner 50V mobylette) to clean.
When I tried to re-assemble the jet, I found that it leaked like a sieve. The bottom brass screw apparently wouldnt seal. I don't remember seeing a gasket in there, but I make one from a tire tube and it sealed up ok.
Is there a seal or not?
If not, how do I assemble it so that it wont leak?
