husqvarna 562,best ported saw ever?

[mdavlee]

Whatever you done worked.

One of my favorite features of the 562, is the ability to port a brand new saw, and send it home with its new owner ungassed, knowing it will not need its carb adjusted to avoid damage. The AT takes care of everything. I also have been amazed at how much of an air leak the AT is able to compensate for. We have had saws come back in for repair with blown base gaskets, leaking trans covers, bad crank seals, torn intake boot, and a blown case gasket, and the cylinders still in excellent shape.

This is really why Autotune was created. [emoji9][emoji9]

This saw had its squish band cut, pop up turned on the piston, and .070 removed from base. It has a LOT of compression. When the squish isn't to tight, a simple base gasket delete, and strato timing change gives really good results. The compression increase and lower exhaust gave this saw a much wider happy range than those that only have a gasket delete.

What are you doing on the strato timing Alan?

I just grind the piston to make the strato timing match the intake timing, so that both the intake and strato ports begin to flow at the same time.

Dang nab it, I wanna drink the kool-aid!!

I ran one of Randy's 562's. Really liked that saw. Cut smooth as buttah!

It seems some saws really like a pop up piston, perhaps not just for the compression increase alone, it appears the re-direction of transfer charge helps scavanging. The straight shot over a flat piston perhaps is not the best way on certain saws. It would be interesting to see how a change in the upper transfer angles would work on these saws that like a pop up.

I see. I've never altered the relationship between the two. I'll have to try that.

My 2260 is intrigued by this thread

I'd Like to Run a Good 562, really, I would.

The only one I've ever handled was in pieces in a box.

I can't see how one would compare to a ported 77 cc saw, but what do I know?

Compare it in what way ?

In smaller wood the displacement advantage is useless , like any tool its built for a purpose..and it shines in its intended purpose.

 

[KenJax Tree]

With 20" bars in 14" wood a 562 will shine but with 28" bars buried in hardwood a 77cc is gonna shine

 

[jmssaws]

28" bar buried i prefer more than 77cc

 

[Benelli777]

ok but a 20 inch bar in 18 - 24 inch wood is my goal for my 562.

Bigger trees I try to let them grow for my kids children lol.

Good goals.

 

[jmssaws]

A 20" is all I'd use on it. I've never had more than a 20 on my 460.

Not that it won't run it,I have bigger saws to run a 28".

Is my 084 better than my 346xp ?

Is my 661 better than my 201 T ?

I've been debating between a 60cc vs 50cc as for a limbing/bucking downed tress for Syrup purposes.

Can anyone give a pro vs con of the 50 vs 60 debate? Both will be ported 16-18 is my max bar length. The 70s and 90 cc saws have the bigger stuff handled lol

A 2260 is hard to beat..real hard.
