Chain talk

[jmssaws]

That will be a good test chain to show the power ,am curious how the chips are gonna look .

 

[jmssaws]

It takes mucho ponys to run it.
The chain on the 7900 is 3/8 but pretty good too,9pin on it

Don't put .404 in the7900... I want to see it do good within it's limits lol

7900 will run .404 if called on to do so..

That's right, if it had to it could

One hard to over come issue with .404 is its hard to reduce chain speed & increase torque with a sprocket swap. A 7 pin .404 sprocket is bigger than an 8 pin 3/8. The old saws that had much lower max rpm and put down their power at much lower speeds overcome this but today's high revving saws make .404 a bit challenging in oz hardwood. I run a lot of it but would love the option of say a 5 or 6 pin sprocket to slow things down and put some torque behind the cutters.

404-7 is a tiny bit smaller than 3/8-8.

 

[jmssaws]

Stihl doesn't offer a 404 8pin anymore,ain't got a saw that will run it is recon

Mutt runs a 9..
Hell, I'd run a 10 if the freaking chain would stay on the bar... Lol

Need a large mount 17 or 21" shaped for that.

The 7900 has a 9pin on it but it wouldn't like the 404 that's on the 066,it's stronger than the dolmar by a good bit and it's pulling it hard.
The 50" 404 with full comp and a stock chain don't pull as hard as that 20" 404.

 

[jmssaws]

Mutt is also ahead of this 7900.

Not familiar with the "mutt". Explain?

Mutt is a 7900 Matt has that mike built,it's quite stout. Best running one I've ran.

I think John Reilly has a couple that are stronger. The Solo isn't quite up to it and has the longer stroke advantage.

It's a well used 7900 I sent to Mike to do some stuff to. We call it the mutt, cause it's a dolmar with a husky carb and a Stihl piston..

John's 681's are bad dudes..
But I'd like another crack at em with the mutt set up the way it is right now.

I'm sure it would be close. I would like to see a couple of his against that one with the same chain/operator. I'd like to know how close it is without a head and big carb.

He's gonna send me one to play with but I only have stihls to compare,I'll have to send it to you or Matt to see how it does.

Maybe we can get him to come up for the GTG in December.
