Echo Red Armour = semi synthetic

[Ford3000]

This is very good to know.
I'm learning about red armor. I run it in a Echo weedeater. I was starting to have visions of a tear down.

Like a lot of things, Red Armor doesnt appear to be available where I
live, yet they sell the big hp saws and dont support them with an oil
that would better stand up to the job.

My spark arrestors and catalysts went bye bye a long time ago. How well does it do with an open exhaust? I'm using it at 40:1 right now.

It will depend on the temprature your saw is running at, and the tune,
high temps will burn more of the oil, though some say its not the oil thats the
culprit but the additives that are left behind that are not properly
burned off, its them that we are seeing and not so much unburnt oil.

Where do they not sell RA?

I was thinking of the oil laying on the flat in the picture
above, if it could run down the inside of the crank towards the bearing, it
would have a better chance of doing something productive.

I’m of the opinion (take it for what it’s worth) that gravity has very little to do with where the oil goes in the crank case.

Oil on a slope should run down that slope, unless there is an obstacle,
am not blamig gravity.

Base gasket delete ?
Muff Modded
timing advanced or just plain ported Turtles ?

How does one muff mod a turtle?

You know what, I don't really want to know...

We've got a thread for that...

By special invite only.

I read somewhere many years ago that 2 smokes lube via mist in crankcase and the oil precipitates out on the metal surfaces so position is irrelevant.

Even when said slope is rotating at 12,000+rpm?

This is one of those situations that I'm okay not being one of the kewl kidz...

Context of reply was with engine running, surely.

The picture shows a stationary engine, its not spinning, there is oil
laying on a flat spot of the crank, it looks to have ran down the piston
and pooled there, I wouldnt expect oil to hang around if it was spinning.

NO, the context was

I agree, but the image is of a pool of oil, that is the oil I would like to see
making its way onto the crank bearing, and having a sloped surface where
it pooled after running down the piston would help.

Ok, more logic here? A bearing at rest does not require lubrication. So regardless of oil pooling location it does not matter. More or less oil on a resting bearing makes no difference. So is this a moot point?

 

[Nutball]

What if they made a channel in the transfer pockets on the case that funneled oil down into the bearings when the engine is off? Sounds like a good idea, but I often find very little oil there, and I find that strange. Everywhere else is oily. I'd think more oil would collect in the transfer tubes and run down, but I guess it stays blown dry while running.

That bearing presents the most difficulty to replace, which is why I would like to see every opportunity to lubricate it addressed. We can replace the top and the mains on a rebuild, not so much the big one down there.

Well logic tells me the more oil I can get to a bearing the better chance of survival it has,
so even if it's not currently moving, being soaked in oil is a good.

3 more tanks might’ve had it all cleaned up

Y’all other turkeys are silly to think non-E Fuel & Red Arma @ 36:1 isn’t the way to go in a chainsaw.

From weedeaters to blowers to top handle saws & felling saws, they all get the same at my shop & I don’t have burnt up saws from RA mix.

It’s y’all’s money: spark plugs are cheap.

I have a lot of customers bring me equipment with plugged up spark arrestor screens. They are usually running stihl ultra.

Stihl Ultra sucks in large quantities.

Plus it smells like a mixture of burning water bottles full of cat piss.
