Speaking of cleaning the spark screen/muffler reminds me of our cheap Homelite string trimmer. It's the wife's favorite because it starts easy and is lightweight.
It started out as my FIL's. He ran it for several years and then couldn't get it to start. Figuring it was "old", he just bought a new one. Gave the dead one to us since he knows I'm good at fixing stuff. I had to puzzle over it for quite a while before I found the muffler exhaust tube was completely packed with rock-hard mud thanks to some dirt-dauber wasps. Has run great ever since, probably another 10 years now. I did whittle out a little wooden plug for the muffler tube to use during outdoor storage and tied it on with a piece of cord.
