So Mitch you were the first to port one so it seems in North America, heck maybe even over the UK guys too.

It looks good. Maybe husky made a 50cc saw with enough power for me. :D

That ported Dan Henry 346xpg 50cc I ran at Ohio gtg with just 346 heated carb felt like a mini 372 in the cut. Andre's 346 50cc with 357 carb felt the same way. Strong.

I've run a 346 built by Andre, owned by Mike.  It is a solid running saw to be sure. 

Didn't do anything drastic to this one, making improvements that fared well in its big brother.  This new series responds well IMO.

Can't wait to see what Ed comes up with.

Mitch curious what the ported 550 autotune rpm's sets itself at out of the wood. I set my ported 346's fat around 13.8 for firewood cutting etc.

No idea as the tach goes nutty.  Fastest recorded rpm by the micropr was 14100 though.

Just played with the timing a bit.  Anything at or past 1/3 key will not allow the saw to rev.  Settled on approx 1/4 key.  Will measure that out later.
