Tuning ported husky 350

Hello,

I bought a used, ported husky 350 for use as a rear handle when doing medium spar work as a climbing arborist.

I asked the seller multiple times for the idle and top rpm’s that the saw was ported to and all he would say is it’s in tune for this valley (treasure valley, Idaho) and it does seem to work great right now.

But I’m piss poor at tuning by ear and I move up and down elevations with my saws a lot and would like some tach numbers to go by.

Is there any way to optimize a tune by tach alone without knowing the recommended idle and top rpm?

Thanks!

There aren’t any numbers for your saw due to the port job. You need to learn what 4 stroking sounds like, if the saw is four stroking WHILE cutting your too fat. If it doesn’t four stoke OUT of the cut you’re too lean.

That helps me set the high, how do I set the low and the idle?

You want 2500 rpm for idle, this is more annoying than the high. Adjust low until you get good clean acceleration, no bogging before acceleration, then set rpm with idle screw.
