RE: Rossi engine
The idle is set pretty lean, but I still get an rpm rise when I pinch the fuel line at idle. The transition is like flipping a switch; idle to full power in an instant! I could probably open the idle needle 1/2 turn and still be OK-I'll try that and see.
This set up is on a friends model, and I offered to trade him a smaller Rossi carb for the 10 mm (I think I would like the 10mm on my .65).
Thanks for the offer, but I like the boost from the big bore carb for my use. My friend doesn't need the 10mm carb on the .45 so I will probably swap him out of it.
