Tuning a Clearing Saw

[landlubber]

Hello,
I have a Stihl FS450 that I'm freshing up with new lines, primer, OEM carb kit etc. I would like to know how to tune it correctly. FS450 is a 44cc, traditional 2 stroke.

The saw has a limiter on the H screw that I can pull off to adjust and I have a Digital tach. I know how to tune chainsaws but I'm not familiar with the clearing saw. I would assume there is a limited coil on this unit and I was going to find the limited RPM then fatten it up until it comes down from that RPM but I'm unsure of the correct method. There is a cutting disc on the saw now.

Thanks for the help.

Hopefully a pro will chime in but your on the right track.

I found that the limited RPM and MAX RPM listed are 12,500. I tuned it to just over 11,000 and it works well.
