If it is below 3000 RPM while cruising, you are probably not engaging the main jets. Thus changing them will not help.

When cruising under light load, the low speed air jets are metering your fuel. Frankly, you are out of luck adjusting these bad boys, unless you have a carb modified for adjustable screw in air bleeds. ie, QF, Demon, DaVinchi, etc. These are smaller jets accessible from the top of the carb on each side of the shooters. As the jets meter air, reduce their size, to enrich your cruise mixture.

Of course, it is helpful to have an A/f gauge to actually know what is going on.
