I was mowing a lawn with said lawnmower running well, stopped half-way to empty cutting box, couldn't restart. I yanked on the pull cord but didn't unwind like usual turning over the motor.
Pulled on the cord as hard as i dared but no movement. The lawn looks terrible, please help!
I bit the bullet and rang up mountfield in the end. they explained the piston was stuck through suction to the end of the cylinder with some oil.
to fix it I had to remove the sparkplug and then pull the cord. to remove the oil I primed it 6 times and pulled the cord 6 times still with sparkplug removed.
