Full throttle walls eh. Beastly.

Measured my prop. Its a good 21 3/4 inch so not far away from the stated diameter. Anyone tried the Chip Hyde 22X8 wooden prop? Also checked my main needle setting compared to what the manufacturer says and its in the right area so I dont know why its burning so much fuel. Will still lean it out a bit.

How long do these petrol engines take to run in by the way?
