Hi Kevin,
First of all, I may have mislead people with my Kawasaki "upgrade." The Briggs ran just fine until it began to start very hard, then I switched it out. Turns out it was just a troubled fuel pump. Starts like a champ again (I sold it).
I split a lot of knotty ash. I don't expect it to power through at full speed, but it does shift to the high pressure stage very often and slows significantly. I can't outright say there's a problem. Overall I am very happy with it and recommend it without hesitation.
I bought it new in June 09 and have probably split 12-15 cords with it. I haven't changed the hyd filter yet - maybe I should (maybe partially blocked?).
Also, the wedge sharpness is about the edge of a fifty cent piece or dollar coin. Should I sharpen it?
Lastly I am sorry to derail this thread from the original SS intent. I'l buy the first round...
Thank you for any help! Da Hack
