Jet starting point for new port


Recommended Posts

Just getting my new port cyls put on and wondering what main to start with. I am runnin cpi's , 34mm mikuni flats, plate at 0 and dyna on stage 2 at 2000ft , 19cc domes on 110/91 blend I ran 320 mains on old port 196deg exhaust 127deg trans and 123deg boost. I now have 198deg exhaust 130deg trans 126 deg boost and 2mm widened main transfers. Roughly where should i start with my main jets?

Can port, but not jet? Ok..... Well. Try upping the main to a 370 and work down. Maybe a clip richer on the needles and 30 pilot. With the size of those carbs the pilot may like to be a bit larger since there won be much off idle vacuum on a set up like that.
