yeah you tune to the "correct" tune, obviously not just turning screws till it wont 4 strokeI hope you’re considering the tune of the carb when you say that. It’s better to tune a saw a bit rich at, say 13,500 than having it screaming high with no 4 stroking, say 14,700. Easy way to toast the saw is to run it lean thinking rpm is the way to go
get it to 4 stroke out of the cut and the second the chain touches the wood it should clear up, how I tune all mine and they all run great, only ever blown one up with bad mix
