Tore Apart my 661!

[Evansaw]

Howdy all...

Last year about the same period got a brand new never gassed 661CM v3.0 assembled with a jug and mm from the Jack Daniels territory

Usual suspect was a southern gentleman mostly trying to decide between turtles and pies.

saw was running AMSOIL SABER 1:40 as it's the best oil i can get here apart from manufacturers stuff.
MaxFlow filter used green for the most part.
Initially used for logging firs with 3/8 1.6 various lengths and from last September i was running 8t .404 at 20" and 28".

Let's have a look how it all started

And today a year after I decided to give a thorough check out to get my stuff ready

and then...

NEVER EVER IN MY LIFE FOUND A JUG AND PISTON LIKE THIS.

Spark plug never changed so far

Muffler on a clean and dry side

Hey that guy can actually build a jug

NEVER EVER BEFORE in my life saw a jug like that. ITS BRAND NEW!

Piston skirts have mirror finish

Piston in General has minimal carb

 

[Evansaw]

Even the piston rings are like new in box you can actually read the code letters. No gum around. Absolutely fine condition

 

[Evansaw]

Piston has light carbon that you can actually read the letters

Kind of amazed to wipe it off with soft cloth

Back together and a beautiful sea view of the Aegean Sea in a Greek Island.

Oh it's just my Amsoil mix

Randy builds a wonderful saw. Reliable and long lived, like a saw should be.

got a few of them

but i was really amazed with the efficiency of carbon fouling absence

The mtronic system is also excellent, at work we have a ported 362c that the plug is a perfect color and the muffler is also dry.

Good oil for sure. It’s on my list of favorites.

I've rebuilt two 661's, one run over by a pickup truck and the other run over by a skidder. Each required $550 in parts alone. Hardest part of the repair was removing that outer handle. That used to be a piece of cake on the 660. Amazing thing was that both ran fine when I was done.

Hi buddy

not really sure if it's the oil or the engine efficiency and I would not like to go in depth at oil threads as i m unlucky enough to live in a country with minimum choices.

What I consider worth mentioning and propably should turn into a scientific research is : HOW a southern chickenlegged oxygen consumer scratching blended metals can create an efficient motor engine like this when at the same time he cannot decide if he likes more pies or turtles!!! AMAZING lol!

Randy is a legend he wouldn't need me thousands miles away to speak about that. But it's the first time i see such results in any engine.

It could just be the light on the saw.
And let's not to forget about my weird eyesight.

The piston looks to be oily, just as we would want it to be.
But for some reason, that big end of the connecting rod and crank shaft looks dry, in that photo.
Again, let me say.... that sometimes the digital photography and the internet plays tricks on my eyesight.
but It just caught my attention as I scrolled through the pics.
but it is late here and I'm tired , so could just be my eyes and brain messing with me.
