Wow! I'm impressed already. The saw runs very strong right out of the box. The muffler is not choked up like we're used to. However, a simple muffler mod did make a noticeable difference. I then proceeded to advance the ignition timing about 8° and wow what a difference. This saw loves this simple mod. If I didn't know any better, I could believe that this saw was already ported. That just excites me to think what it's going to run like when it is!

how much percent do you increase the outlet?
Double the size of the original outlet?

Yah , that saw is “hot” out of the box stock ... assuming the same feed pressure by the operator, the cut times (with the muffler mod and then the muffler mod and timing advance) weren’t much quicker than stock (or the same or slower) .. sounds hi-strung with the 8+ deg advance (at least to my ears ) ... they are available in Canada like you see and with the wrap handle ... not sure about arctic or adj carb model but they are available in select countries
Chain’s pretty dern tight

How much gain do you estimate can be attributed to break in?
Little, if any. It's only made less than a dozen cuts. The changes were immediately noticeable after each mod, especially the timing advance.

I just got finished watching the video. The timing advance made a big difference. Does it work that good on a 261 ?
Here are some pics from this afternoon.
This before the powerhead had any fluids in it, completely dry.
Full of fuel an oil.

That's odd!
Not bad at all for a stock saw. No spark arrestor screen in this saw.
New small style plug.

It helps, but I don't think this much. Admittedly, it has been a while.
For reference here is a dry 562xp. The 462 is amazingly light for its displacement.
I would love to see the thermal imagines on the cylinder compared as they made changes to the muffler. Love how they cut the useless parts of the finsHere are some pics from this afternoon.

Hey Brad, have you checked stock squish? Stock gasket thickness?

Word is right around .030 -but may vary slightly due to tolerances ... check with solder to be sure !

The timing advance really made a difference.
I haven't checked anything like that.
