Would like to know wheir I can buy a repair manual for my Kioti LK3054?? I have a oil leak that looks like it's coming from the valve cover or the top of the engine??, Where can I buy a valve cover gasket?? also the throttle control leaver does not hold the rpm's, I use a piece of wood to brace the throttle rod to keep the rpm's up while cutting grass and weed badgering. I would apreciate any help with these problems---crankman
