Modding The MS261

[Mastermind]

IMHI, a 260 will never be a 346 or 261. Putting a bigger carb on a 260 is not a simple bolt on ordeal. Then you have to figure it how to make the choke work, which I never did. It's just too far behind with to many obstacles. Then you're still left with with old school AV and horrible filtration. Now, in not talking about race saws here. I'm talking about being able to build a fully functioning production capable saw.

I agree completely. The 026 was one of the first saws I modded and over the next couple of years I've built a pile of them....and I've learn was tricks that will make em run. They will make a strong 50cc saw but never will they be a 346xp.

The videos are processing. I don't have any way to edit video (I wish I did) my wife bought me this JVC video camera at a pawn shop without any of the software. JVC is not user friendly when it comes to working with just any editing program.

I'm happy with it now. It has a butt load of torque.

I'm sure I could get more upper rpm power from it but Darren asked for a saw with torque.

The timing numbers are still stock. I raised the exhaust the amount I lowered the jug....never touched the intake....and just leveled up the transfers. It's at about 190psi so raising the exhaust would be my next step. I really need to move on to the next saw though.

Same bar and chain on a new MS460 for comparison. The large dawgs got in the way but you get the idea.

Looks good, Randy. Much stronger.

That 460 looks familiar!

No faster in small wood, but much stronger in big hard stuff. Port timing is still very mild, just leveled the transfers and opened the tunnels. Oh a bit more compression too.....it should end up at 200psi. I could do another one in one step now. :msp_thumbup:

It should.

I have a new dual port cover for that saw.

Well put her on it! I will pay for it. Been meaning to contact ya anyways.

This 261 has cost me a few days but I've gained some much needed experience with this saw. I've got a cold and my help is down sick too. I can see the work piling up.......I'm shutting off this laptop and picking up a wrench.

i think that looked like an amazing amount of torque out of a 50cc saw. i want a 261 just like this one for grunt on bigger stuff and i want a 346 turned up for high rpm for limbing and small stuff.

i think i just invented the perfect 4 saw plan-
346
MS261
441C-M TRONIC
660

Here is my current 4 saw plan:
346xp ne
MS261
MS361
MS460
All 3 Stihls are new, not a scratch on them! And, all 4 will be modded in time!

I was thinking the same thing. I hope it doesnt hang with that 460 when he is done with it!!!

 

[chopperfreak2k1]

i think he was hinting that he needs to move onto other projects. he can try going farther on mine though!

You might need some PPE and some Depends, when your eating up 660's and such.:msp_scared:

SEND IT!!!!:hmm3grin2orange:

I have one particular 660 in mind...:hmm3grin2orange:

 

[jropo]

Well if you have a 460 cutting like a 660, might as well sell the 660 and get a 880 for MM to do!!!!:hmm3grin2orange:

Nah, do the 660 up to take the 880 :msp_thumbup:
