This a pic I took tonight of my 036. It was rich and Keith tuned it leaner. This was the original muffler and looked like this when I got it. Piston and rings are new. I've had it nearly two years and used the same mix as my 660.

Dang thats a nice lookin ported exhaust!!!???

If it starts to seize, yes.. but running a saw pig rich because your paranoid about a seizure is ridiculous.
Mtronic and Autotune are your friend..

I'm running the same mix and see my exhaust port.

Might actually lead to more ring wear given that excess fuel washes the cylinder as well...not to mention less power, more emmissions and worse fuel consumption. There is simply no good reason to run a saw rich like this.
This is exactly why Autotune and Mtronic are a good thing IMO.

I've never heard of a 661 mtronic go over 13600 on a tach WOT. That's were I'm tuned.

How is your plug color compared to my saws ? Tan colored or more black ?

Not sure but I'll take a pic. Good idea.

I have several cords of wood in my back yard if you want a pic of that too. Same goes with several friends I've cut for.

That that proves what? I have 20 cord cut, split and stacked in my yard right now and another 5 down on my property blocked up. Big deal..

660 plug. I'm definitely rich!

You don't have a 661 though...

I cant stand runnin pig rich saws , it takes more effort from me to keep them loaded and cuttin good..i dont see the advantage ?

I'm just repeating the WOT rpms from AS members I've asked that have them. Also, what I've read on AS. I'd like to hear from additional 661 owners of their experience.

Nothing but a disadvantage..

And that pertains to your 660 how? My ms260 isn't lean at 14,600, but that doesn't stop knuckle heads from running them at 13000 rpm..

BTW the 661 is rev limited I believe, so that 13,600 figure is meaningless as a measure of tuning.
