Worked on a power torque the other day with the boys. Throw away piston on what must have very few hours on it. Fitted second hand piston and rings but was still over speeding.. Engine was choked with carbon. Four blades fitted with this machine, is this normal? I thought they were just spare lugs, when you have thrown the others out. Suspect the user pushed it too fast in high turf. Any ideas guys?. A so called mulch mower.! Nice wheels! Crankcase pressure seems OK.
