My weed eater one riding lawn mower all of a sudden the muffler is getting very hot. puttering as well. Any suggestions
 
Pull the engine shroud & make sure the fins are free of debris.

Is it running any different otherwise ?
 
Sounds like it's running really lean for whatever reason or the plug/s is either wrong or has issues. it could also be a couple of other issues. I would especially check the exhaust valves and push rods.
