hi all. newbie here, trying to be a mechanic. my 22 hp kawasaki engine on jandeere 445 mower starts and runs great, until with a full load such as when mowing at full throttle it backfires, loses power. using partial (almost full ) throttle helped for first 2 mowings but this time it got so bad could not continue to use. i noticed for several years it tends to diesel (run backwards) when you shut it down. could this be a timeing issue? i put in all new fuel at the start of the season.
