> Yet chainsaws ... well, they're just a different beast. > There seems to, weirdly, be more poorly designed engines or some such. It's about power and weight. You don't carry a push mower; the engine can be heavy and powerful. A trimmer doesn't need much power; the engine can be light and low power. But a chainsaw: You have to carry all the weight for long periods, and yet you need a lot of power. Relatively speaking they're hot rod engines with a higher power to weight ratio. That's why they're generally harder to start and burn so much fuel as well. > And it's not normal for them to always have issues. People make a living off of them. Correct. Drain the fuel, every time. If you let the mix evaporate and leave behind gobs of oil, you're the problem. When storing for long periods put it somewhere heated to avoid condensation cycles. No problems.
