Hi,


I live in Southeast Michigan, about 600 feet elevation. I have my 2020 Brozz 250 currently with a 120 main jet, one washer on the needle and always 87 octane, no ethanol fuel. I started with a 105 main, and moved to a 115 for a few hundred miles, and it seemed it was still a little on the lean side, looking at the plug. I am currently finishing up a port and polish, so I got a real good look a the head, ports and piston. It is running a little rich. I guess I'll wait until I see any impact from the head work. I would rather a little rich, than lean. I would think 115 would be in the ball park for 1000 feet.



Thanks,
John
