There's another thread by Modified Mark dedicated to these saws if you are interested in learning more. You get what you pay for but they will do the job if needed. They are funky to tune and usually are way too lean out of the box.Picked one of these up today for my favorite price . I am now the 3rd owner.
I know zero about these. But, as advertised, it did not run. Pulled the carb (pretty easy) and slotted the needles to accept a flat blade screwdriver. I know I should buy a proper driver. Monkeyed around with the settings and found that the original 2 turns on both L & H were way too lean? Quite a bit richer now and it seems happy.
I didn't cut with it yet but my first impressions are: 1. Easy/smooth to start/restart. 2. Oils well 3. AV seems decent 4. Found a cool scrench holder under the footpad
I imagine these would be really zippy with a 0.325" 16" setup.

16" with full 3/8 will wake it up a bit. These saws and their little sibling the 4218 are sold with bars are far too long for their power output.
