064/056 mag11 build

[hseII]

I advanced the ignition and ran the 064/056 some. I'm still limping it at 12k but it's still strong, the rpm don't change much.

Is it Ready for the Big Bar?

I'm to afraid of the piston coming apart to turn it any faster than that,if I take any other saw I got and turn it down to 12k this saw will clobber it but will it gain a couple thousand rpm faster? It should and we'll find out tomorrow.

So does it only effect no load tune? Or is it also weaker in the wood ?

It tunes just like any other saw,it just stopped at 13.4,I'm not talking it stopped 4 stroking I mean it stopped as in no more rpm. Put a stock muffler on and at 1 and 1 it was 4stroking at 14.7

Well we need to find one that will stay together.

Very interesting build project. Thanks for sharing all of this information!

I guess a TS700 piston would be bad too?...

Either OEM or does Meteor offer?

As a recap on Pistons, what's the verdict?

MS661-
TS700-

A aftermarket 056 piston should be here tomorrow.
The piston in it ain't no good,the pin bosses are sloppy and the ring grooves are beat out.
I'm not kidding when I said the ring gap is 070

I believed you the first time.

Considering how Hard it is to source another good piston, I was asking if other Stihl offerings might be an acceptable alternative.

Not that I have found.
I thought I was going to have to use a 395 piston but thankfully thereis a aftermarket one.

I'll probably raise the exhaust when I change the piston.
Maybe a little bit more intake

I got the covers on and run it up to 12.5 and held my breath. Lol
I ran my 2 old saws for comparison, there at 13.5

Your own 066 really rips!

Yes...yes it does!!!

My 2 are close but I'm surprised that the 064/056 is so close turning a 1000 less rpm.

No replacement for displacement!
