If it bogs down like it's getting too much fuel, turn the low side screw out about 1/8 of a turn at a time until it will rev without bogging. If it chokes down like it's not getting any fuel, you probably need to open up the high screw a little.
BTW, you can determine which screw is which by looking at the carb at the base of the screw...it will have a L for Low or H for High stamped near it.
I think you want the oil/fuel ratio; 50:1 Fuel/Oil Mixture
Use a quality 2 cycle oil and mix it to the OIL supplier's recommended ratio. Today I use Stihl 2 cycle oil mixed @ 50:1 in a Pioneer that I purchased new in 1980. There are no gouges or scratches on the piston or cylinder and I have no carbon build up on the piston top. The manual (on stone tablets) recommends 24:1. Over the years the mixture has leaned from 24:1 (Saw Recommendation) to 28:1 (Lawn boy mower recommendation) to 32:1 (Oil provider 8oz/2gal - used for many years) and finally the last 5 (±) years 50:1 (Stihl 2.6oz/1gal)
Any fuel containing ethanol is not good with chainsaws. Mix what you expect to use within a few months. Anything over 1.5 months old use up in a 4 cycle engine. HTH
