661 Oil Test 32:1 vs 40:1 vs 50:1 ?

[blsnelling]

Just trying to learn something is all

Please remind me what the 100C viscosity is of Amsoil. This thread is much too long to dig through.

 

[porsche965]

Not sure on that one but I think in the 11s

there we go thanks

 

[bwalker]

That is a factor of tuning, not mix ratio. The way I understand it, mix ratio should be determined be observing the amount of oil left in the crankcase.

That marketing consultant is confused...

Motorcycle carbs are a lot different in the way they they feed fuel than the carbs used on saws

 

[bwalker]

Motorcycle carbs are a lot different in the way they they feed fuel than the carbs used on saws

They work the same basic way.

 

[bwalker]

Because of its intended market...ultra high RPM road racing motorcycles.

Which pull about the same rpm as a 50cc saw.

 

[blsnelling]

Which pull about the same rpm as a 50cc saw.

But with a MUCH higher BMP on the bike.

 

[bwalker]

But with a MUCH higher BMP on the bike.

True. Most everything has a higher BMEP than a chainsaw...

 

[Moparmyway]

@bwalker ............ curious to your response ..............

Lets say that you are running your saw through 30 large bucking rounds.
You finish your last cut.
Do allow your saw to;

A. Idle for a few minutes to cool down, then shut the saw off with the kill switch
B. Rev it up to WOT and shut off the saw with the kill switch
C. Idle for a few minutes, then WOT for a second and while at WOT, shut off the saw with the kill switch
D. Hold WOT through the cut, keep WOT as you pull the saw out of the now cut wood and hit the kill switch while holding WOT
E. Something totally different

 

[redbull660]

Got some K2 to test thanks to Moparmyway!

and I got a new hat... Gotta love the beaver!

 

[KenJax Tree]

I think K2 is my favorite of the oils i've used, but it gets expensive.

 

[bwalker]

I think K2 is my favorite of the oils i've used, but it gets expensive.

Its very expensive. Nearly double the price of 2R.

 

[bwalker]

@bwalker ............ curious to your response ..............

I just shut it off when done cutting.

 

[Trx250r180]

I have lost track ,but is it ok to use stihl mix in a saw ?

 

[SAWMIKAZE]

I have lost track ,but is it ok to use stihl mix in a saw ?

No , it will blow.

my 361 (purchased new back in 09') run only on 50:1 ultra.

not sure why the rings and piston skirt are so clean...while the top of piston and the exhaust port have a hard layer of Black carbon on them. The layer of black carbon is also thicker than I would like.

must be why stihl sells the black bottle jug that says decarbonizer on it
