At engine shut-down...Joe
What kind of engine?? My Kohler does the same, try letting it cool down for a couple minutes before you shut it off. I usually let my mowers run on half or low throttle while I trim and shut them off after, usually solves the problem.
Yup - just what he said ^^^^^. Let is cool down for a minute or so at an idle before you turn it off. My Kaws will do the same thing.
Because the engines are shut down by cutting the power to the spark plugs. The gas keeps on flowing into the engine and lights on fire without the ignition from the spark plugs.
what is wrong about your mower back firing? does it hurt the motor or something or is it just the sound of the back fire?
My Kawasaki also does it at low idle, My dealer told me to increase the engine speed a little this will burn off the fuel more quickly at shut down. Where at low idle the fuel does'nt burn off as quickly causing it to build up and backfire. That was over a year ago and it has'nt done since.
Simply shut the engine off at FULL throttle and no more back fire! I don't want to risk shearing off the flywheel key with the backfiring. We have shut the units down at full throttle for many years and no problem so far.
my kawasaki backfired the first couple of times i used it but it quit the more i used it
let engine idle a minite ,then hit full choke it will stop in a second ,no air no nothing .
thats a good way to foul out the plug(s)
