STHIL 271 Farm Boss Died and Feels weird trying to pull start.

[Splinter35]

Hello everyone. I have a 271 Farm Boss and was working on the oiler. I emptied the bar oil tank and poured some kerosene in it. I shook it up and emptied the tank well. I then pull bar oil back in and then ran it without the bar to see if the oiler would take back off.

It did and while I was still running it start to bog just a little and then died.
I started to pull start it again and the pull cord feel weird. It won’t turn over.

I pulled the spark plug out and cord feels like normal. I put it back it and it goes back to feeling weird.

I run 2 cycle high quality fuel in it and it was running the 2 cycle fuel at that time.

Any help would be appreciated

First step, pull the muffler off and get a look at the piston. Sounds like a case of piston scoring.
