Hate to say it, but if you don't use the chainsaw regularly, it will probably fight you every time you go to use it. I got rid of my gas one and got a 60v Dewalt several years ago. Works great with no hassle.
A tip for our millennial frIends:
The key to a reliable chain saw - or any gas powered tool which may sit unused - is maintenance. The main thing being to drain the fuel and then run it until it completely burns all the fuel remaining in the carb and hoses - every time it is used. This is a pain to do correctly, and requires starting and nursing the thing several times to completely burn all the remaining fuel. But it works. For me, it also works better than using something like Stabil fuel conditioner.
Leaving raw fuel in a small engine for any extended length of time will gum up the works in short order as it varnishes out. That is what causes 90% of the running problems.
I have a big-ass 70cc saw with a 3 foot blade, and a few gas powered trimmers which I use maybe once or twice a year. I’ve never had a problem getting them to run reliably when needed.
