261C break in period

Attached some pics. 32:1 mtronic v3, have not performed reset, just at the end of break in period

Interested in opinions on breaking in self tuning saws

Put mix in them and run it.

What oil are you running and did you do much part throttle / light load cutting?

 

[Bruiser1]

I give it about four or five tankfuls wouldn't rev it WOT unless you're in the cut. I believe everything needs to seat itself valves,rings

Part throttle is about the worst thing he could do.

 

[lone wolf]

Just use it as normal, but don't work it super hard and build a lot of heat, like in a stump cut with a dull chain. .

You have to load the engine up to seat the rings. Just don't hold it wide open for extended periods of time for the first 6-10 tanks.

Sorry for the late reply, I've been away. I'm using the stihl premium that I got for the double warranty. I have been doing alot of lighter work but I make a point to run it hard in some random log when I do to try and mitigate it. It's supposed to be my firewood saw though

Bad in terms of breaking it in specifically? I don't like doing it but I've had to do a lot of limping unfortunately during this time and I had no other saw so I increased the oil mixture and loaded it up hard in big timber to try and offset the light work

Run it wide open but don't overheat it.

Hottest I've seen it was low 300s, im particularly careful about letting off at the end of the cut but I'm concerned about the carbon. Since I have no input outside of my oil mix and the trigger I'm left with either the saw doesn't like limping or doesn't like how I'm limbing...

It's no secret that Stihl markets the lowest quality oem oils.
With that said your motor looks fine. Run it and run it hard. Twoncycle use ball and roller bearings which require no break in. The only break in that is needed is for the rings to seat to the cylinder walls. High load is the only way this happens. Running the saw lightly when new is very counter productive.

Get better 2 stroke oil and run it like you stole it

I've read this before about stihl oil, and countless other threads until my head exploded.... I plan on switching to something that's less questionable. And getting a couple cord dropped off soon. Curious to see how it cleans up. What's the recommended amount of seafoam to put in a 2 stroke?

Joking, I'd sooner give it away. Thanks for the input

 

[HansFranz]

Nothing wrong with Seafoam. I've had it "clean up" 2-stroke carbs that I believe were starting to gum up from old mix on a number of occasions. YMMV

I cant say the same, never used it. It's cosmetic oil, lighter fluid and ..... alcohol.....
If I wanted it's cleaning properties I'll just use the naptha

The reccomended amount of seafoam? None. It's snakeoil.
Your motor isn't dirty anyways. Just switch to a FD oil and stop obsessing.

Yeah I said that right here

Good for you, go for it.

(It's interesting that most of those who say Seafoam is snake oil have never tried it, but most of the people who say it works, do so from experience...)

(Also interesting that the naysayers all act as if they're chemical f$cking engineers, listing ingredients, when Seafoam's composition is a trade secret. Gotta love copypasta Internet Folklore.)

Its no secret. The SDS lists the specific chemicals used and their approximate ratios. The exact percentages aren't specified, but there's no magic secret sauce.
