Ok so since my RT carb is running a little rich on the 75 jet, but way too lean on the 70 jet, I had the idea of mounting this Delta 40mm 5VDC Fan AFB0405LD-R00-The Electronic Goldmine onto the air intake to force air into the carb. Then put in the larger 80 jet. Power would be from white wire, so the more you rev, the more extra air you get. It pulls about 1 watt. Think something like this would work? Not just to fix the richness, but to boost performance as well.
