What do you do with 700 cords of wood a year? Do you run a full time firewood buisiness?
Well that would be a full time job . You could heat the average home on just the bark that fell off of that amount . :D

Big saws like the Ms 880 etc have their place but generally speaking aren't needed in most cases . I have 4 of over 100 cc plus one that only resides in my shed it being an 084 . They don't see much use .One reason a large saw lasts forever unless they are abused .

BTW a brand new 880 with a 42" bar is pushing two thou from a dealer .For that amount you could buy a little saw,mid sized ,90 cc and have enough money left over to go out to dinner .Maybe enough to buy a case of beer too .

Yeah, like 13 1/2 cords a week for 52 weeks a year :-O..I have an 084 and love it! But my next smaller saw is an 034.

I don't even think about using the big saws until it gets over 30 inchs .In Ohio that doesn't happen that often .

I do try to run them enough to keep the cobwebs blown out though .

When I was cutting much more than I am now I had predicted the big saws spent a  grand total of less than 5 hours per year among all of them .

The 084 in my shed which belongs to a tree trimmer spent less than that .Fact is just the time I spent running it at a GTG was the only run time it had gotten in two years .

Yes maybe, but think about it? At 700 cords I plan on buying a 880, 660 and a 460 this year, bought two last year almost wore them out. The point being, do the math? It is a small price to pay for what you get out of it, oh and no, it is not a full time job, just something I work on the side at 10 cords a day or so…. Thanks for posting.

I cut usually around 100 cords a year, some years a little more and some years less. Depends on the year. I use a 044 and a 372 for my firewood saws, they will cut anything I need. I've had that 044 since the late 90's, been rebuilt once but shows no signs of giving up yet. If there not cutting firewood, there bucking logs.

Even 700 face cords is a lot of firewood.

Reading the OP post, he has not mentioned 700 cords of firewood.
Just felling 700 cords of ponderosa pine.  :)

OP said he would still use the 660 to limb and fell so that would leave me to believe that he wants to buck with the 880.

yes i am planning to buck this wood in rounds for firewood, actually we handle a lot of this wood by hand and i was thinking of ripping large timber in half, that would be rounds larger than 25". at least we wouldn't be breaking are backs loading wood splitters. thanks

for 700  cords you could probably justify a firewood processor. Lots less work.

Im starting to convince myself that i can justify building one and i only use between 5 and 10 cords a year  :D
Either that, or spend some of the money making my house more energy efficient ::)

I’m trying not to get this post off course, but by the time you drag a wood processor into the sight, skid logs bigger than 6” (with some ten thousand dollar) skidder over to a seventy thousand dallor wood processor that they claim will cut and split 7 cords an hour, I can do just as good with a saw and sharp chain. We don’t skid logs, I chop them into pieces right where they fall, load then and I bet you that faster than a wood processor, “skidding logs take time and machinery, and wood processors take both”, thanks everyone for posting…. Rob :P

the exhaust exit on the muffler needes to be 75% the size of the exhaust exit on the cylinder. pull the limiter caps on the carb and tune the saw with a tach to 13500-14000. without a tach tune it til it four strokes or burbles.
Factory spec is 12,500 - 13,000 rpm.   Some saws like to run faster, depending on this or that.     I'd recommend using a tach in any case, unless the OP already has a well calibrated ear.   

You can just open up the existing muffler hole rather than buying the dual port.

7845Robert, it would help if you would edit your profile to show your location.    What I'm getting at is, what is your elevation ?

All saws lose power at altitude.   The 660 is especially affected by altitude because it usually comes from the factory with a tame compression ratio and excessive exhaust duration.     The result is a narrow power band that's short on mid-range grunt.    I can understand why a 660 would be bogging in 36" ponderosa pine if it were at several thousand feet elevation, with the restrictive factory muffler, and perhaps a poorly tuned carb.

But I don't think an 880 is the answer, unless you are built like superman.     Focus on getting the 660 running better.   Try the improved muffler and tach tune first.   

If that's doesn't do the job, consider having a 660 woods ported, with a pop-up piston to raise compression.    It'll cost you several hundred to have the work done, but like you say, this is a business for you and time is money.

Keep us posted.
