I'll make another vid with the same chain.  Curious to see how close the Dolmar is to the stihl

Adam, just a "baby" Bobcat!! Lol works great for backyard tree removals.  Non turbo so it's a little sluggish at Times.

The 460 sounded like it was straining a lot more than the Dolmar.   Pretty cool saw you built Adam.

Didn't want to throw rocks but I noticed the same thing as Roger did. RPMs make da noise, torque do da work!

Think the 460 is a little lean on the top end and chains weren't equal imo.   I'd like to run a few tanks through the Dolmar to see if there is any carbon in the transfers like before the addition time area was added to the exhaust

I'm curious if anyone has tried using a small primer bulb in lieu of a choke butterfly? Thinking of removing the choke shaft and installing a small nozzle to spray a shot of fuel into the venture.  What would the drawbacks be?

Adam I remember a hotter woods ported 026 that ran the primer bulb set up (even though choke set up was different then your talking, the choke was still bypassed).  I ran the saw at gtg's a few times and primer set up worked good.

Thanks Kevin. Was curious about this, do away with the choke shaft and shutter, might make a small improvement in airflow.

I have worked on a few 2 stroke ice augers that do that.

The predecessor to the 6400 Dolmar pretty much did exactly that. The Dolmar "i" models all had a Tillotson carbs with a squirter right off the carb pump when you turned the carb choke lever on. None of these had an actual choke.

Saws like the 6000i, 6800i, 111i, & 115i would all do this. In cold weather these saws will start and continue to run with the choke lever on. Turn the choke off as the saws have run a few seconds.

These saws are no longer in production.

Yup I have a 120Si like that, easiest starting saw ever built.

Maybe find one of those carbs Adam and see if you can put it on the 6400?
