It was the same with my lawn mower. It only gets used maybe 6-8 times a year. For some recent years here were how many days it had been idle before each use: (245, 22, 14, 15, 14, 33), (258, 24, 12, 13, 17, 11, 38, 71), (167, 21, 21, 20, 15, 61).
Two simple things fixed that:
1. I switched to gasoline that does not have ethanol added.
2. Once every 2 to 4 weeks in the off season I start it and run the engine for a minute.
The container I use to store gas holds about two years worth and the mower runs fine on the the two year old gas. I do add fuel stabilizer. The bottle of that claims it is good for 2 years but my previous bottle was 6 years old when I replaced it and the mower was fine on 2 year old fuel with 6 year old stabilizer.
If you live near any body of water big enough to attract boats you might try at marinas. CENEX also often sells it. Here's a site that can help you find it locally if you are in the US or Canada [1].
I do not do any winterizing procedure for the off season. I asked the repair place I took it too one year when it would not start before I started doing #1 and #2 if winterizing was necessary if you were running it occasionally, and they verified that you only need winterizing if it is going to not be used.
100% agree on the ethanol-free gas to reduce carb gumming.
For overwintering, I just detach the hose after the fuel filter and drain the remaining mower fuel back into the can. Or, on small push mowers where this isn't possible, use the fuel shutoff and just leave the gas in the tank.
Then run the mower until it dies. Doesn't take more than a minute.
Finally, unscrew sparkplug(s), pour a teaspoon of motor oil into the cylinder (keeps rings from seizing/rusting).
Leftover gas in the can gets put into vehicles at the end of the season so I'm not storing stale gas.
