661 R&D

[Redfin]

There should be one on the 441 if need one .I think they are kind of in between a 7 and an 8 tooth 3/8 if remember right .

Top to bottom. .375/7 .404/7 .375-8 .375-9

that cylinder only has 012 from the chamber and 175lb compression and no epoxy. lots of work in the transfers though and thats where the power is.
absolutely clobbered my 066. lol

. Did u ever think it would?

I think that a 7 tooth .375 is best in timber. That's just what I prefer. Used an 8 on and off and there was something about it I didn't like.

Looks old and dry. Whats the difference in the 661 Jason? The quad make a difference over the 2 ports or the mtronic adjusting the saw to the different loads? Seems to me it should be a job to outguess mtronics as many times a sec. As it adjust? All 3 saws look dang good

it was cut this past spring and has laid in the sun since so its hard as it can be.
green there not as bad.
i love the mtronic on these saws,it has the old boot,coil
i tried the updated coil but it seems to take some grunt away.

ill get a pic of the 404 8pin.
its just a little smaller than a 375 9pin

i only use a 7pin falling,the saw is much more forgiving.

i have to be careful with a 7pin on my 066 trying to keep it loaded enough so it dont grenade. the 661 is stronger but it can take care of itself.

i thought the 056 would be ahead with the 32"

I used to be completely biased to the running a 660 only. The 661 is definitely a work horse and a game changer. Unless you get one that's problematic..... Been there done that.

i love a flat top 066 but if i was cutting timber again id be running a 661.

as far as this one is ported the mtronic works perfect,its always tuned and ready.

I good strong flat top. They are great. I had one for a good while, I always said if I could hold onto the saw and push it though a tree with my feet it would take it like a champ and just pull through it and work.

661 sounds good. Maybe I'll run it in December

got a few videos loaded with her phone
new 404 full comp that i hit with a double bevel a couple times and a giant 8pin,i dont have anything else that will load a saw like this setup does.

Love the distinctive 661 sound. I've never heard one sing quite like the video I just watched. Very nice Jason.

You gonna send this saw out for us to play with Jason?

 

[jmssaws]

thanks for the kind words men.
its the best all around running saw ive ever built,its cool to have a saw this strong and it be so well manerd.
im sold on mtronic. this saw is some kind of stout and enjoyable to run.
I can beat it with the other cylinder,it will gain with more bd

REAL NICE!!!

Ive been thinking about the "why" your seeing better results with the 4700 coil J.

Mine ran very well with the 4700 until I put a Maxflo on it which makes absolute sense. More air, more fuel needed.

Iirc some had seen the fuel issue which was thought to be a rich condition but after some study turned out to be a lean fuel curve with the 4700.

You are at 800' right? I normally cut at 2100'. Do you have a Maxflo to run with that coil or maybe try without a filter? Just thinking the Mtron cant fully compensate for all conditions.

If Jason milks every last drop of power out of her and is happy , and it's back in time me and John Boy are planing on going to MasterMinds gtg.............
