Gas mileage

[THEFERMANATOR]

@4300 that 150 looper is burning close to 14-15 GPH. So a 35 minute run will consume roughly 8.2 gallons one way plus another 8.3 gallons the other way. Let's say conservatively you use 3-4 gallons in your start ups and shut downs while drifting, you come out to roughly 20 gallons used. Your 35 minute run one way yet ony 10 miles total for the day doesn't add up though. It wouldn't hurt to check for leaks, fuel slicks while idling. But it sounds like your off on your distance a bit. It also sounds like your propping is, my V-20 with an OLD 1.6L sea-drive cruised close to 20 @ 3800-4000.
