I have a tecumseh ovrm120 6.5 engine that has a timing problem. It kicks back and pulls the pull cord right out of your hand. For the life of me , I can't find where this engine's timing is set . no points-mechanical or solid state, the pin hasn't been sheared. Any help would be great. P.S.  My sister said hit something when it stopped. The blade shows no damage. the shear Pin looks good...Help

  there is the flywheel key located underneath the flywheel.  this key controls the engine timing
