I do, do I as I say!!!! My tiller has been running rough, so I decided to take the carburetor off and give it a good cleaning. Took it off, opened it up, cleaned out all the gunk inside and put it back together and back on the engine. Started it up, did a little adjustment and had it running like new. Ran it for a couple of minuets and shut it off. Was picking up tools and got of balance, so I reached over and grabbed the tiller so I did not fall. Well, just let me tell you----------NEVER GRAB A HOT MUFFLER.
