sheared flywheel key. YouTube has vids... type in mower cord backfires & you'll see instructions on how to fix it.
Mower backfires and won’t start
because it is a worthless piece of junk!
to much fuel is going to the engine for it to burn it all
It's lean. You have to figure out why.
Should not back fire upon start up. Replace ECTS and see if that helps
sounds like the clutch switch neeeds replacing or cleaning.
If it is running at the time it back fires your timing is off about 22 degrees. if it happnes when you are trying to start it then you timing is off 180 degrees.... Your intake valve is open when the spark plug fires.
It depends on if you bought a pull start mower or a power mower. The pull start mower will have a handle you have to pull hard to start it. The power mower should have a button that simply turns it on. Make sure there is gas in the pull start mower.
AnswerSounds to me that your vehicle is off time. Check the timing on it. If the timing is off it will backfire through the carb and also if it is cross wired (firing order wrong) it will backfire through the carb.
"I stopped trying to start the lawn mower out of frustration."Or"I am frustrated with trying to write a sentence about frustration."
There are several reasons why your mower will not start. There could be an obstruction in the blade, a petrol mower could be low on petrol or the fuse could have blown in an electric mower.
you tell me the year ill tell you why
Could be in need of a tune-up.
