As I mentioned earlier, my property is badly overgrown. I had a working electric chainsaw among things my dad left me when he passed away, and there is also a gas one that needed a little bit of help.
I pulled the cover from the top and swapped out the fouled spark plug. I also hosed out the carb with a healthy dose of carb cleaner.
The saw had thrown the chain off the bar. In addition to this, the chain had rusted.
There was quite a bit of sawdust and oil mixed together. I cleaned it out with carb cleaner and a rag.
