I need one of those lifetime warranties lol.
Run it for a while without the muffler, if it continues to run fine then you know the problem is in the muffler. Pull out the anti spark screen (if you haven't already) and see what happens. Still have problems? Clean the muffler as best you can, beat the heck out of it, de carbon it, fire??(don't know). still having problems just replace it $25-$30.
