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

[redbull660]

It's all in the chain and the operator, and 33 or 36 RS is plenty aggressive right out of the box. It's up to the operator to be able to feel and listen to his saw and operate it accordingly.

1. do you have a .404 bar for a 661?
2. have you ran .404 on 661?

I've personally ran .404 and 3/8ths RS, RSLF, RM and customized RS half skip on 20", 24", 28", 30", 32" 36" and 41". On the 661.

I'd rather not have to apply pressure that is required with 3/8ths on a 661. I'd rather use the .404 wish is pretty much self feeding and more consistent than trying to equally apply the pressure required on a 3/8ths chain during the test.

What you are saying is incorrect and that's just the bottom line. I doubt you've even run 404 on a 661. You have to press on 3/8ths to get it to cut as fast as .404. ...on the 661.

on 661...

3/8 RSLF requires the most pressure
3/8 RS H next
3/8 RS next
3/8 RM the least pressure required to get it to cut fast and right.

Id like to try 404 on my 390 with a 24 b/c for noodling

404 RSLF is the noodling king on a torque saw IMHO of course.

So Redbull the 404 self feeds better than 3/8?

oh for sure. on a 661 anyway.

Ive only ran 1 stock 661 with a 32 tsumura bar with RS but I was totally impressed

I still prefer a 395 over 661. I'd love to put one on a mill and see how it would do. That may sway me towards getting one

Never had my paws on a 395. How does it compare to a 660 and a 390 Mike?

Stronger and heavier.

 

[KG441c]

Stronger and heavier.

Oh ok. Id assume u like the 395 for milling over an 880 or a 3120? 395 is alil on the heavy side for firewood say in the 20 to 30" range? You would pick up something alil smaller? Im really liking my Hybrid in wood from about 15 to 25 and anything smaller I pick up the 241c and anything bigger I get the 390 out

 

[mdavlee]

Yeah they work great for up to a 42" bar. I mostly use a 70cc with a 28". Been playing a lot with the 50cc stuff lately.

I wouldnt mind a Dolmar 7910

 

[mdavlee]

Yeah. Those are about my favorite all the way to 90cc

 

[KG441c]

Yeah. Those are about my favorite all the way to 90cc

Firewood cutting 20" to 25" wood. PORTED Hybrid 440/460, 7910, 390, or 660?

 

[bwalker]

Yeah. Those are about my favorite all the way to 90cc

How's the solo 681 compare?

 

[Trx250r180]

.404 full skip square is what i am running on the hybrids ,running full comp .404 ground at 10 degrees for milling ,i do not get why people say .404 is too much unless you have an 880 size saw ,works fine on my saws if it is sharp ,it may add a little weight to the bar ,but i have not noticed a whole lot ,the wider spaced drive links oil better on my saws also ,a 32 inch bar 3/8 has 105 dl ,where the .404 has 91 or 92 ,i have to count again ,on the same 32 inch bar .

I have never seen a piece of .404 chain in my life. It just isn't used locally.

There ............. now you cant say that anymore

 

[Moparmyway]

I am supprised at this numbers given the substantial wood. I would have that they would have been lower.

Forgot one last, but very important piece of info .................. running square filed chain

 

[Trx250r180]

I have never seen a piece of .404 chain in my life. It just isn't used locally.

it has a slightly taller cutter ,and a little wider kerf ,looks like this ,this is round ,the skip i have is square ,i convert the round to square on the grinder

I have used square chain once. I had poor results hand filing it and gave up. It is not used locally either.

If done properly ,it is like adding 10cc's to your saw for power ,it is also much smoother ,not as hooked as a round profile ,so not grabby .

3/8 off the grinder ,(yes moparmyway ,i know the gullets are not cleaned out )

 

[KenJax Tree]

For my use square isn't worth the time, so semi chisel for me[emoji20]

 

[mdavlee]

How's the solo 681 compare?

Its a touch stronger.
