Does anyone happen to know what the factory carb setting are for the Rossi Black Magic?? I've had one in my Inferno since the day I got it 4 years ago, and once I got it started the first time it has been the best and most trouble free engine I've ever owned. It could sit for 6 months and start right up, and I never once made any adjustments to the carb after the first 3 break-in tanks. The other day I tried to start it after a couple months of non-use and it fired for about 3 seconds then died. I've changed plugs/gas/filter/glow igniter/etc and have had no luck. Being an idiot I didn't check to see where the needles were set before I started adjusting them, and would like to start over from the factory specs. Anyone have any advice? Thanks in advance.
