True, but.... I'm fairly mechanical, and I've had no-start problems with gas equipment in the past, too, until I learned not to ignore the maintenance schedule. One problem, if you want to call it that, is that many OPE engines will tolerate being neglected. To a point. If someone buys a new gas mower, and does nothing to it but add gas, it will still likely last 3 yrs if it's a 4-stroke. For 2-cycles, they will last longer as they will get fresh oil in every tank of gas... until the exhaust screen plugs. Then you learn to stop running at part throttle. Then there are those who DO follow the maintenance, and after 5 yrs or so, it still gets hard to crank because the valves need adjusting. If you follow the maintenance schedule, including valve adjustments, and always run your equipment at full throttle, it will last decades. Or, at least, they used to. Equipment built 10 yrs ago would do this. Now? I'm not so sure.
Now if someone is the type who just adds gas to their gas mower until it dies, they will also likely be the type to run an electric mower until it stops, then change or charge the battery. Completely draining a battery every time is a good way to shorten it's lifespan. So these people will still be replacing their mower every 3 yrs.
