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

[cuttinties]

The rpm they tune at is a function of port timing...

How much money do you want to bet me that I'll prove you wrong on that ?

 

[bwalker]

A well scavenging 2 stroke will have wash marks on the crown. This saw makes power from scavenging because it's so low compression it has to.

If you say so..

cuttinties - your wasting your time with this guy

It's only a waste of time if I have something better to do haha

Most of them have very little run time on them as they are hobbyists.
And expiereance AS members. I have been here longer than most on this thread and have more expiereance with all kinds of two cycles to boot.

Would you recommend racing oils like H1R and Motul 800's for Hot saws?

Here's the piston

I can't see anything

If you're so knowledgeable please show us some of your work oil god. Mr.Iwasherefirstandthatmakesmeright

How.much you got?
I could build an engine that reved to 20K , and not be lean in the least..

You said that it depends on port timing. But if you want to build it and we can race.

It does.. you can lean out a boat motor all day long and it won't hit any were near that.

You think you can get 17k out of durations lower than 155?

 

[Sagetown]

you've posted over 200 times on this thread. Zero evidence on any of them. Don't you have anything better to do?

Red; your inquiry convinced me to change oils, and all I have are stock saws. I'm using Lucas right now. When it's all gone these two just came in the mail, and I'll go with them. H1-R looks to be a lil more oily than does the 800.
Thanks again for your endeavors.

This is my choice...if i want cheap, clean burning, and readily available on a Sunday, or if i want an ester based full synthetic oil that IME burns the cleanest in MY saws.



You guys are NUCKIN' FUTS

Please explain your theory on compression displacing oil?

My theory on it is. More compression= more bearing load witch=less oil wedge in bearing cage/race and rollers/balls.

 

[cuttinties]

In all seriousness I don't really care about any of the hoopla here. I'm not bothered by certain people's opinions either. I'm really just poking at bwalker because he's yet to state his qualifications beyond being on AS since 2002. If he were qualified and could provide proof of building saws his thoughts may carry more than 6 pages of posts.

It is my understanding that AV gas is for planes only.......

But much of what I thought I knew is coming unraveled.

So should the AV gas be used in saws that fly?

 

[blsnelling]

Those things along with blowing all the oil out the exhaust.

Then why are none of us experiencing this? It's contrary to everything these oils are built to do.

 

[blsnelling]

I'm still reading along waiting for someone to say why H1R is not a great oil.

I've read that it is not........but have read no reasons.

It's time to explain maybe?

No one can. It's one of the best oils on the planet. I think I've settled, for now lol, on 800 2T, H1-R, and Mobile 1 2T if I can get some. I've got a friend trying to hook me up. Obviously, money is not in the equation for using these oils. For someone that's burning a LOT of fuel, I MIGHT choose a different oil. That oil might well be something like Yamalube 2R or Baileys Full Synthetic. They are fantastic oils, but I simply cannot believe that they are superior to these others. Needed? Maybe not. Better? Absolutely.

Greater film strength means more protection. H1R, Motul 800's, and R50 have those qualities. Their Spec sheet data means something. Also, my muffler never has oily residual in it. I'm tuned to 13.5K and pushing over 210psi in a 90cc saw. When I look inside my cylinder there's a difference with Motul 800 off-road and Stihl hp ultra. I'll stay with Motul. I'm sure H1R and R50 are excellent also.

Say it ain't so brother!!!

 

[RedneckChainsawRepair]

Somebody a page back ask. I wouldnt use any of these oils in a hotsaw.
