I have a 14 horse kawa. Every 2nd or 3rd pull on the starter it kicks back real real hard . It almost tears my fingers and arms off.Is there anything I can do to correct this problem. #2? can I pull the mower back.In other words can I push down on the pistol grips so the deck comes sraight up so I can clean underneath the deck or will the oil get to places in the engine it should'nt. Thanks for your answers.
