I only buy ope from repair shops/dealers never big box stores. I have 3 Echo machines, a Husky chain saw, Toro 2 stroke snow blower, B&S powered pressure washer, mower & generator.
I keep spare parts on hand for all of them mostly carb kits. Rebuilding those little cube carbs is pretty easy. I try to run everything once a month but if I know it’s going to be too much of a hassle I drain them & run them out of fuel. I know a lot of people use the canned fuel but I continue to mix 89 octane pump gas with a good 2 stroke oil like Echo power blend.
Anything with a bowl type carb you should fit a shut off valve to prevent fuel from leaking if the needle valve leaks & it makes it easier to drain the carb. Old fuel left in a bowl type carb will evaporate & leave deposits. As soon as you try to start it those deposits will clog the main jet.
