This one ranks quite highly on my list as of right now.
Tread lightly young Skywalker...
Ok... I posted weeks ago, but after today: @Rattler ported 371xp. Awesome!

I like my 562 the best and since it's been ported it's fun to lean on in the cut without slowing down. But my favorite is the 660. Even though it's such a fat pig, when you blip the throttle the tree falls over and blip it again and all the limbs fall off.
MasterMind ported 346xp last couple days.
Nothing like a horizontal cylinder Mac - an real man's tool!
Thank God .
I've always liked the design of those macs. They look like they are interesting to work on.
They are actually very nice saws for limbing and trail clearing, with more guts than one might expect from 32cc. It's very light and perfectly sized with a 12" bar with a large tip diameter. There are 35 and 38cc versions too.
Without A/V they vibrate too much for serious use, but the A/V springs are unique and NLA. I'm looking at other springs I can retrofit or modify.
It's a major improvement over the previous MiniMac due to the rotated ports, which allowed the carb to be mounted up top. Unfortunately this creates a flaw in that the thrust face of the piston runs over the transfers, which reduces surface are and causes wear on the piston skirt. There are other saws that share this problem, and it's not that big a deal. More detail here: http://www.arboristsite.com/community/threads/mcculloch-se2012s-mac3200-a-v-conversion.277788/
Here's one for you guys.
Just had a customer give it to me, it was appreciated 3ven more since there was a bit of customer created difficulty on the job.
That's a nice saw! Hard to believe it's still in that nice of condition.
I like my Dolmars sized for the job at hand from a 112-79xx, when the really big wood comes around then the Stilh 084 comes out to play, 120cc of pure nasty and a 4 ft bar.
Has been a popular simple mod
Since the 371 came out
No grinding on pricey oem cylinders
Especially back then
I've only used open window 268 pistons
Haven't tried other types
Do your hutzl saws still run?
Im not sure if this is directed at me or Czed, but in any case, the only hutzl (farmertec) top end in my saw arrangement is in fact in the 372 right now and its the bb kit. YES it runs and runs well, I just want more UUUMMPPHHH out of it. Ive built 2 other 372s for a buddy using farmertec BB kits. One of them for whatever reason, seems to be a FANTASTIC saw. The other one ate a clutch side crankcase bearing and subsequently the clutch side case as well. It actually was my fault it went down because I didn't freshen up the bottom end when I built it.
268 farmer tec piston cut the circlips down.
fuel line's are crap replaced with echo bulk line
Chain brakes are sketchy some work
A few tripped at idle.
One kill switch had to be replaced
Cut for over a year with it
How many hours?
I've made some good runner's out of the ft cylinders
Took some grinding.
Squish on some is very high
The 268/272 pistons closed the gap
Going from 130/140 comp with a 372 piston to 170s
Of course i could've had the base cut to adjust squish
But i would have to ship them to and from

I thought a belt sander was sufficient
