Modding The MS261

[Jwalker1911]

So far the best thing about this thread.....I see someone mentions a 460 for sale.......I went to youtube and watched a ton of build videos the difference is amazing but you guys need to buy bigger stoves you cut pretty small chunks of firewood

I run 93 non ethanol with Belray H1R at 40:1. It's at 13,800-14,000

I really like the Belray as it mixed with alcohol. That way if ethanol is in the fuel it still mixes well.

At what point in porting do you benefit from a richer mix?

It's my understanding that more oil in the mix seals better and makes for more combustion pressure. I never really worry about the splitting of hairs as I only build saws for work. I just like knowing there's plenty of oil in the mix.

Also a rich air/fuel ratio runs cooler.

So do you use that mix regardless of wether a saw is ported or not?

Yep. That's what I run in everything including my grandson's dirt bike.

Good stuff Darren. That stringy has to be rough on a chain cutter. We have nothing here that compares to that. I guess skidding logs through mud to the landing makes for a dull chain too but nothing on this mountain grows with sand inside the bark.

The 261 is on the way my friend........I hope it suits you. :msp_wink:

 

[deye223]

yes randy i think it will. that tree was about 60' got some vids there were not very good but the best i could do today , once you get the bottom half done it's pretty clean , i'm gunna put the vids and some pics together later

and once again thank you very much

The way the wind blows here in Kansas we end up with a lot of sand and other enemies to a saw chain. Not to even mention nails, railroad spikes, etc. Always find them damn things with a new chain too. :bang:

I usually start inventing new cuss words when I find stuff like that with a chain. I need to quit that since my kids are starting to venture out with me now that they are old enough...:taped:

Nice mate dont ya just love Stringy,nothing is easy with Ozzy hard woods.

Know that you are getting into reall saws (ported ones) if you are not using fully synthetic oils i strongly recommend ya do,have a word to Matt about the oil he uses.:msp_wink:

my bad i allways thought stihl oil was synthetic , matt gave me some JAKmax synthetic i'm on me way out the door to get some more caltex 96 RON

 

[Stihlman441]

I nomally use Caltex 95 untill 2 weeks ago they have changed the smell of it and even when its gorne through the saw is very un pleasant, maybe to stop the dark people sniffin it.
I have been using BP Premium 95 and all is good.
