Dayton..
..Still saws like a scream'n demon
takes 30 wt. oil for the fuel mix,i kind of lean it out a bit
,,really oils up that chain very good when you hit that oil assist button,
strapped on a Stihl chain,,had it out cuttin up firewood on an elk trip and a few camping trips.
All in all not bad for 5 bucks from a yard sale over a year ago.
The only thing that i had to do to get it running was adjust the air gap/ pickup coil .
