As Z said, the Poulan 46 should be great on the TX Hurricane. I have mine going on a Robinhood. It has a MenzS 20x8 for starters. I will try the MenzS 20x10 as well. The Robinhood is my aerotow/candy drop/parachute drop plane. My initial run of the engine on the 20x8 was in the 7100rpm range. I am sure it will get better once the ring seats.
