I've got a Dolmar 420 here that's going to be put through its paces. I wanted to get a little fuel through it before going to work on it. I took it out this afternoon and cut...and cut...and cut...and still only ran about 2/3 of a tank of fuel through it. It does very well on fuel consumption.
I already reported in the other thread that compression is very high on this thing. I'm talking 190-195 PSI! And that compression is obvious in use. Even on the first tank of fuel, I buried the 16" bar in red oak and it just went right through it. No kidding, this thing has excellent power as it is.
It's bone stock with the exception of no cat and the Euro front cover. First impressions are very good. I really don't think this saw is intended to compete with the other 35-40cc micro saws. This saw is a cut above that.
Build quality appears to be excellent. It's built with a vertically split magnesium crankcase and bolt on cylinder, two bar studs, side chain tensioner, spring assisted recoil...
Where am I going with this saw? Well, tomorrow I'm going to build a log stand so that I can properly run the saw in timed cuts. I'm going to first time the saw as it is. I'll then mod the muffler and time it again. After than it's coming apart and getting ported. Of course, I'll time it again with the same B&C. Once done with that, I'll be testing it with 3/8 lopro, .325, and .325 NK, with different size sprockets. This will be a fun project and will be interesting to see what this new Dolmar can do. Stay tuned for updates.
See, I can get a saw dirty, lol.
Nothing in the carb.
It cleans up nicely.

A real pleasure to run!:greenchainsaw:
Kudos to Dolmar
