Naw, that's not the trick - there's plenty of mechanisms used every day for such purposes....

The trick is matching reliability.... How many cycles is a modern starter motor designed for? Half a million cycles? Maybe a million cycles? A former job of mine was inspecting/analyzing failed power springs connected to motors

Given the loads on a chainsaw (even a lawnmower) and how many cycle uses - it makes sense not to have an electric start - even moreso because the input is human power
