Does anyone know about where my old Homelite VI955 should be running at , I'm guessing this saw is about 25 years old and fairly big size wise but not sure of HP or C.I.  I'd like to set the hi speed mixture with a tach and see how it runs , is this the prefered way of adjusting saws or is setting by ear still the best??

I set them by "burble".  First do the low speed jet, then set the idle, then richen up the high speed until you get a bit of burble at WOT.  Check the transition between the low speed and high, and you are done.

So many trees, so little money, even less time.
