your pick for the strongest 81cc and under saw

[old 040]

Not as strong as my 181 but still a very fun and impressive saw to run is my PP415......

Dolmar PS-7900 hands down!
Stock with muffler mod in my case.



I'm also extremely impressed by my stock muffler moded Dolmar PS-7300 & Dolmar PS-7310.
The later really needs a removal of the SLR to wake her up.

Granted, I've never ran any other saw brand in this class - and I'm honestly not looking to!

Solo 681. I've yet to run a saw stronger stock saw for the displacement. I'm not sure I wanna put any bets on a stock 660 or 390xp knocking it off in a hurry either. I use my ported 660 more as its tough & set up for work, but whenever I pull out my minty 681 for a run its simply impressive. I'm hoping the 5 cube MS500i will one day seal the deal on the strongest 5 cuber. Hopefully the revive of the 5 cube saw is coming & husky offers one up. Its by far mu fave class of saw. Done well they have the weight of a 70cc saw with the power of a 90cc saw, that's kinda what the 681 is IMO.

Are you Canadian by chance?

It almost seems that you might be trying to disparage the greatest nation on earth with this statement... However I likely need another coffee or 3 to try and figure out how...

Dolmar 7900/10 is my favorite saw of all time for general purpose up to 28" bar. That being said...the 281 Mr Rattler did for me is a Monsta!

Doesn’t the 681 have issues with the crank coming apart or something like that? Just curious, as I heard of something along those lines.

They have had some issues in commercial use.

Tig the crank ends and be happy

Got a little of run time on my 281 at the pnw gtg this weekend and its a bit of a toss up now between that and my sp81...

 

[sawmikaze]

As far as ported saws go, my "Stumpbroke" MS440 would be next in line....View attachment 128006 View attachment 128007

I miss stumpy, his little fat ass made me laugh

7900 is my all time favorite saw. I had a ported 440/046 at the same time as I had a ported 7900... and the 7900 had much more power. I have a 665/7910 now, but haven’t run it much.

I recently tuned up and restored an Echo CS-8000 and was very impressed with it. It's been replaced by the CS-800. Not the lightest saw in the world, but it's built like a battleship. It's sitting right on 81cc. No decomp valve, so it starts about as easy as pulling my Stihl 064.

 

[Wood Doctor]

Here is my CS-670, the next size down from the CS-8000. I pull a 28" bar with it most of the time and use a bar adapter that I made in my shop so that I can run all my big Stihl bars with it:

It has never seriously objected to either a 30" or a 32" bar. Starts all the time, runs strong, never bogs down, and it's a keeper. My 046 Mag is really jealous of this saw, and so is my Makita 6401 with a BBK. They keep asking me, "Edwin, where did you find this beast?"

Video of it beating the 046 and 6401 with same B/C?

 

[Lee H]

Guess I need to take 181 fo a spin and see what all the hype is about.
I may need to git me one. Then bore it to 56mm.

No, the whole plan is to find a 181 that still has an OEM top end, I owned a nice low hour all OEM and stock 288 and still feel my 181's run better....

I fear it would be impossible to supply this video because I would have to run all three saws and all bars and chains would have to be identical. That's the way it is.

If you look at the combustion chamber in an early 181 cylinder as compared to a 288, they're about half the size.

I got a couple out in the shop one is mine one is ranchdadmikes

Yep, I know JJ, that's what makes these run so well....

Have you tried a carb swap on one yet? I've tried the RWJ-4 and the results were pretty good. I'm doing an HS-296 on my next 281 build.
