I'm a 32:1 guy.

I like to have the chainsaw rich enough to where I can hear it four stroke when free running and then clean up into two stroking when in the cut.

This works pretty good on the old Homelites and Macs but some newer design chainsaws will not four stroke until above 14,000 rpm and they have to be set with a tachometer. There's often the rpm limiter that trips at 13,000 that you get into which will sound rough like the four stroking that causes confusion. All the more reason to use a tachometer. !2,500 to 13,000 is a good free running set point on the newer chainsaws depending on the saw and the limiter set point.

I the limiter starts working, the tachometer will go nuts and you will not know what the rpm is.
We should share what we know... someone may learn...
That knowledge can live after us... and that "Pays It Forward".
Be all that you can be . . .
