:) or is the the blubber rite before the
saw hits max rpm ,,what u should adjust for.thanks tm
ps if uthink u mite start a pissin contest with u answer ,,an email would be appreciated ,,and ill lkeep it to myself.:)
 
Take that 026 to the wood pile and set the carb.If it's too lean you'll be able to tell it,won't have as much power or feel as strong in the cut.

Tony, I think you will find your 260 cuts best when set to a max no load rpm of around 13,500. I know this is not what the factory says, but I fooled with mine quit a bit and it made less power at higher rpm's.
 
thanks for the dope fellas.. ill slide her back to 13.500 and start from there. i do agree the real test lies in good hard cut ..i was just looking for a good starting place and rite now im involved in other work. thanks again.
 
Ben,
With all do respect, the best RMP comes from a combination of factors. One important factor is chain speed. Chain has an optimal speed at each level of power. So your saw may cut best at 13500 while the same saw with a different pitch chain or sprocket size may operate fastest at a different RPM.
So what should be done to optimize the cutting speed, is to get the saw running at a no load rpm that offers a balence of peak power, lubrification, and longevity, and then adjust your cutting attachments to give fastest cutting. This RPM, I argue, is usually the manufacturers recommended setting.
What you have suggested is is to detune the motor to the point where peak power matches your optimal cutting speed, rather than tuning the cutting speed to macth the peak power.
I only raise these issues because the year is not over, and that instigator award hasn't been sealed.:)
 
The 260 has no balls at the factory rpm. I dont even bother using the dogs on a 260 tuned to run 14000 or over, because it has no torque in any kind of hardwood.

For cutting wood similar to what is found in Michigan, I would agree with Ben (that doesnt happen very often) and richen it to run 13000 -13500


BTW Supra tuning a saw to run less RPMs is NOT detuning it. Power is about getting the right fuel air mix to make the most power, not getting as many rpms as possible.

Besides Stihl has to claim the the 260 runs 14000 rpms to compete with the 346XP, which at 14700 rpms IS properly tuned for optimal power.
