Try reducing the upper step on the current metering rods a little bit, say to .072 to .073, for a better mixture at light, part throttle high vacume cruise That will make it fatter as you know, the other option is to go to the .107 primary jets and then try the smaller upper step metering rods to see what that gives you What fuel are you using and does it have Ethanol in it? If so what amount currently? If your using the ethanol blended E10 then you'll need a fatter AFR than without it to get it to drive well
