Is running picco on a ported 261 a mistake?

[rumatt]

I absolutely frigging love picco chain on my 241. It cuts damn near as fast as 325 on my 261 before porting.

I've been waiting on the new narrow kerf 325 chain stihl is releasing, but stihl is dicking around and not releasing it in the US, for now anyway.

I'm starting to wonder... why don't I just convert my MMWS to picco? I've read it dulls faster, doesn't clear chips as well, blah blah. It cuts a narrower path through the wood and has a fundamental advantage over anything wider. And I don't tend to have long days with the saw.

Should I give it a try?

My ported 261 runs 3/8” .063 and it’s damn fast.

In my experience, 3/8lp seems to cut slightly faster than .325. (But my experience is limited). I think the saw would be fast with 3/8lp .043. The chain might be more likely to break and sharpening will suck, but you might shave time in the cut. Why not try?

FWIW, 1/4” chain is slower than 3/8lp. Skinnier does not equal faster if the bite is smaller too.

I run full 3/8 .050 on mine. Tried .325 and it was okay but prefer to keep all the chains the same so 3/8 it is.

@PA Dan might have some input. I sent a Picco conversion kit down for his daughter Sara.

I believe it will likely cut the fastest out of the box, as you said the thinner the kerf the better for speed. However as mentioned it has limitations, mostly durability. I find the teeth to dull pretty quickly on my 421 Dolmar, but man it's good cutting chain.

Picco can cut really well, and semi chisel stays sharp for while.

You could run an 8 pin easily with Picco.

Will be the fastest, both through the wood and to the bench for filing.

On my ported 241, picco will break at the links long before the teeth wear if I use it in hardwoods. And the teeth on picco do not last a fraction the time semi chisel on 325 lasts.

I ran picco (Oregon 3/8 lp to be exact) on my Chinese 54cc saw when I got it, stock with that chain it was as fast as the modded one with .325. Then I modded it and the picco didnt load the saw at all in soft wood, you could stand on it and it wouldn't slow down. I could've dropped the rakers way down but that might rip the cutters off so I put .325 on it. In dry hardwood the picco was better than the .325 but I don't cut a lot of that.

It really depends on how your 261 is ported, if you went for max revs and need to keep the rpm up you will like the picco, if the saw has lots of grunt you will like .325 better.

You break picco chains regularly with your 241? (!)

I broke two and learned my lesson.

I'm glad this came up, as I'm thinking about what I want to run on my upcoming 346...

Damn.

Looks like I'll work on trying to find someone who has access to Stihl's new narrow kerf bar and chain and is willing to ship

I had .325 on my 2253 and liked it but when I tried square filed 3/8 I loved it.

Picco is the ticket on 018's modded for chopping tops now on the ground or small limbs. I have been testing 3/8lp Raisman chisel on my 200T. It dulls a bit faster than Oregon or Stihl chain.
Next go is to try Picco or something on 114dl and 91dl milling.

I run Picco on an 024 and an 026. It seems to be a little faster than .325", but these were un-modified chains. I have later learned that 3/8" full chisel teeth on the 76LP chassis is faster than the Picco.

76LP pics....anyone?

I must try that chain in 91dl.
Where to get some...

The depth gauges on the 76LP look bent or twisted a bit.
