Flat squish area with tighter clearance will trap more in the chamber. That eliminates most of the carbon in the squish area.

0.040 huge? The thickness of a human hair is 0.004. So ten human hairs equals 0.040 of an inch.

So you're still wanting to use R50? Viscosity double of R2?

That makes sense

Thats what Bwalker has said since the start of the thread. In the right application you need it r50, 800t and in general firewood cutting r2 will be just fine. The oil burns more completely. Same thing the Maxima tech gave a reason for their thinner viscosity oil when I called a year ago

Is that what Tru fuel uses in their 50:1 cans? K2?

My k2 will be here today. Im no doubt sticking with k2 or r2 in mtronics and r50 in my big cc ported saws in the summer cutting bigwood
.040" is huge in a chainsaw, even stock.

It seems like everyone is deciding on their oils before the big grand finale. What are we gonna do when H1-R is the winner, because its already clear its going to[emoji1]

FWIW.. Took Levi's 025 apart last week and got a crappy pic..
History:
Saw has been in use with a fixed jet carb for 2 years doing general limbing and wood cutting duty.
Maybe 50 tanks of fuel since we had it. Not one of the heavy users.
First year stihl ultra, then switched to Lucas this last year.
40:1
Nice pool of oil in bottom of pan, clean and wet bearings, just a tick of carbon on the crown mostly on exhaust side, and ring grooves clear.
Most of the machine marks are still evident on the skirts, 154psi comp.
Running fine, but Levi wanted to make a couple mods to it.

Impossible....Lucas has solvents and looks dry, that was obviously run on H1-R

I can't run H1r unless I'm in a respirator and that's not happening.
Not sure what they use. I've burnt some of it but couldn't decide on the smell.

In the smell part I think u will appreciate R2. H1r irratated my sinuses/throat

H1-R stinks but the only thing that messes with my sinuses and gives me a pounding headache is Ultra, Klotz just makes me nauseous.

That's why I insisted that redbull660 remove a cylinder once. Exhaust port doesn't tell the whole story.

Well, whatever is in tru fuel smells "ok" and is reddish in color..
Cobey runs it exclusively in his stuff with good results, and I can detect a real unique scent from it.
