What oil is best? and what ratio?

[Deets066]

I feel more comfortable under 14K stumping and noodling. I'm not racing anyone in the woods. Although I've won a few bets with that 660.

Workin tune with a 36" usually ends up around 13,800

 

[Brewz]

Yes but I did run some valvoline today and the saw is still running so I like it too.

What ratio did you run it at?

I'm not comfortable holding one wfo over 14000 to check.

I'll turn the high side and check it in the wood. I may have it tuned where it's not 4stroking at all. On my personal saws I'll tune it to max rpm in the cut,never check no load rpm.

Here is something I have never fully understood.
When you say you tune to max rpm in the cut, what are you referring to as max rpm?

32:1
Fast as it will turn that particular chain.
Tune it everytime you use it.

Last time I checked using 110 Sunoco w/800 it was still 4-stroking hard at 14,400.

Ron, why do you use 110 octane? You are leaving a lot on the table with that much octane.

I liked the way it ran in my 660.....felt stronger than 93. I posted a video on AS comparing the two a few years back. That was my first video and my technique wasn't great. The 110 was faster every cut but results might vary now if I repeated the test.

You should try it again. An engine always makes the most power with the lowest octane that can be run safely without detonation. And I don't know about where you are, but high octane fuel is not cheap. It's a waste of money imho for chainsaws.

Not the stumper

Actually I believe it was that one.

 

[Moparmyway]

Mopar is proud of that one! Ive heard him talk about it quite a bit

Mike made me 2 awesome cylinders, no doubt !!

I might mess with them or sell them, but I'm going to play with all of my 90cc saws and see what happens

I still think that one would be better with a head.

In the last few hours, I've been given some incentive to try giving that exact thought a go !!!

Yep. I need to ship him the one I started. It's close to ready to thin and add a plug. Might have to open the chamber a touch more

Is there anyone who dislikes Mobil 1?

It is good oil ,tuned nice ,has very little exhaust smell ,but the 3 machines i left it in over the winter had. gummy carbs,must not have fuel stabilizers i guess

jughead runs valvoline he said it is good oil , im running 32:1 pennzoil in this

pappy's corn squeezin's had something to do with it.

 

[Brewz]

I'll send you some with the cylinder

All good mate, I have found a local RC car shop that is gong to order me some.

I am however looking forward to the jug

 

[jake wells]

 

[Brewz]

They had the saw upside down

 

[Brewz]

I litre of Klotz Motol ordered and on its way
I have been using Penrite MC2ST but the fumes are offensive.
A bit of pizz revving in the garage and people start calling the fire brigade when I open the door to let the smoke out. It burns your eyes.

So far my favorite has been the cheap ryobi oil which I suspect is very similar to the valvoline.
It smelt good, burnt clean and left a nice coating in the motor

I am looking forward to trying out the Klotz

 

[Brewz]

I also just watered down my 32:1 mix with Penrite MC2ST to 40:1 to see it it helps stop all the smoke and fumes

13 hours and no oil talk?!?! BLASPHEMY!!!
