I have just built a log splitter, it has a 2"shaft 24" stroke, I have an 11gpm 2 stage pump and a auto neutral detent, a 6 gallon reservoir, I have put a 5.5 brigs off a new lawnmower on it and I cant get it to start,feels like there is too much torque to get it started. The pump and motor shaft are direct connect.Is my motor not big enough, if so I have a 17 hp off a riding mower, should I change them out?:censored:
