Looking for max rpm specs on this saw. Right now I have it at 12K and just shy of 1 turn out on H with my 100% synthetic Klotz at 32:1.
Manual says L  1 1/2 to 2 5/8 out I settled on 1 1/8 -   H says 1 5/8 to 2 5/8 out and I went with just shy of 1 turn out to get  12k.  True the carb might need a kit and had sat for years before I got it.

Manual also says CAUTION always tune H side at least 1 5/8 out.  ???  It aint happening she would be so fat it would be a pig. Use commons sense on tuning IMHO.

Also never seen this in print before on sprocket rims wear.  When sprocket has worn out 0.5mm or .020 inch or more replace rim. Measured from top of rim to worn down area.
