I bought a used Rossi.40 on German e-Bay and wonder how to dismantle the brass part on the carb that houses the high speed needle?
Is it screwed from inside carb housing (does not look like it) or just warmed fast? (doesn't seem to be the case either).

There is a small slot/gap (0,2mm) between the carb housing and the brass part which houses the high speed needle. On my new Rossi .40 there isn't any gap at all.

Hi!
I'm a bit curious to why the gap is there...there is no gap on my new Rossi .40 carb.

If it were me I wouldn't worry about it, I would install a lager bore carby for starters and remove the liner gasket, lift the exhaust timing and stick it with 15% nitro - no castor...... It will boogie no worries.
