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.

Were you cutting with it when it died or was it just sitting at idle? Was the plug soaking wet when you removed it? You say it wouldn't turn over with the plug in, is that completely seized solid or just much harder to pull over? It could have developed a sudden mysterious desire to seriously flood and it is now hydrolocked. Pull the plug, turn the saw upside down (plug hole at bottom) and pull the engine over to see if it sprays fuel out the plug hole.
