To fix the jerking rotate your tires and what do u mean by cuts when idling if it cuts off then there is a chance there is water in your gas tank due to precipitation just go to the gas station and put about a full tank but u need to keep a full tank in it when your not using for a while when I was locked up I couldn't let it idle without turning off so I would just sit in it and barley press the gas until it thought it was ok to let go and it ran good till my starter went out and the switching off you probably need to get a new gas pump line or whatever it's called I forget.

have 15.5 yardmachine will turn over but not start check spark plug oil filter changed gas runs fine and blade handle up

IT SOUNDS LIKE YOU NEED TO REPLACE THE CARB I KNOW YOU JUST HAD IT FIXED TRY IT

It’s a bad solenoid. Mine was located under the shifter plate?

If he knows anything about cars, he could have crawled under car & cut fuel lines &/or power or ground wires to fuelpump. Both are exposed under car by gas tank.

your starter bendix is bad
a common problem
any small engine shop will have a new one

I wanted to just give a suggestion...do you go to the same gas station to get gas? My sentra ran horrible because I kept going to this same gas station. My gas would get low and it would start cutting off and trying to cut off. I let my fuel go to almost empty and then went to another gas station to fill up. It hasnt cut of for about 6 months now and I havent returned to that gas station.
