Anyone experience this, look closely side of block caught fire, nobody hurt. Looking for advice on, customer service indicates take to a dealer pay for an hour of "diagnostics investigation". Less that 20 hours on this machine, bought 4 years ago.

 

I'm guessing a mouse nest. I've taken a bushel basket of mouse nests out of LT80's. They really don't need to sit that long either.
Other than that, fuel leak???

Welcome to the forums.

 

Could be a few things that caused that including the above. Small fuel leak, oil leak, charge system could have shorted, mouse could have chewed wires from sitting..
