What is 4 stroking and how can you tell your saw is doing that ????

4 stroking is refering to when a chainsaw is running at WOT (wide open throttle) and is rich enough that is "misses" every other stroke. To tune your saw for longevity run it at the 4 stroking point, to tune it for power, lean it 1/4 of a turn below this point.
