RE: Poulan 46 prop sizes
I just did I Poulan 46 conversion that I tried selling on Ebay. I am using a JTec muffler on it and with the new ring I put in it still breaking in, I get 7800 from a 20x8 black MA and 6900 from a 20x10 black MA. From what I have read I may get 100 to 200 more rpms from the engine when the ring finally breaks in.
