Single middle finger port pointing straight up works best.

Have you ever tried the "thumb pointing down" mod?
Not yet, always tried getting fuel air mix to the top.

That's where the 6-71 mod really shines

Two fingers on the pto side, one on the flywheel side. Then you better be hanging on tight because it's a real shocker.

Four fingers is the most I ever put in... and it has to be a special kind of saw to find room for them all.
Tough time running the belt...That's where the 6-71 mod really shines

I put an extra long chain on the blade (Direct drive), and loop it over the drive pulley. Clutch is eliminated for weight savings.

If I used a 4-71, the guy with the 6-71 would get all the porting work!
You know what they say:
Go Big or Go Home!
The camera is top of the line, but the lens was a little dirty from belt dust.

Ya, that may work but what about that sideways balance....LOL...ST would never approve!!
Would that mean it is now an outboard clutch?

No Clutch. Remember, we're trying to make this light and compact. Every bit of weight savings = less fatigue in the woods.

re: Balance
I see you are not new to the high performance chainsaw game. You have a good eye for details that many would not immediately pic up on (including myself in this case).
I may have to add a large counterbalance weight to the other side of the saw. Maybe I can remove the air filter to save a bit more weight.
With the extra fuel used by that mod maybe mount a big gas tank outboard on the left side, course as the fuel was used up that counterbalance would change causing wrist fatigue. Yeah a solid counterbalance would be better but that adds weight....LOL

Yes the weight is a concern. Definitely a major concern here. I am in the shop looking at this, doing a mock-up... we're getting up over 150 pounds now. I think that is just about all you want to carry in the woods.
Maybe a lightweight bar?

I'm sure you people will come up with some brown note, resonance frequency, gyroscopic effect that will levitate the saw in tandem with a violent, total evacuation, bowel movement.

That 6-71 stuff is "old school". I'm working out the bugs on an intercooled twin turbo. Clearly the only saws that could handle all that is either a 10-10 or a Wild thang.
Leave the 10-10 out of this and focus on Wild Thing or Earthquake.
