Yes tried a know spark plug from a wiper sniper with the same plug.Haven't checked muffler,but I can't see that being a problem after I pulled the cover off everything looks new.The muffler still has paint on it and doesn't look like it has even got hot yet.Even the top of the piston looks new.If you have time around lunch then sure we could go for a look.I do think I need some help with this fellow.
