The best version of the 026/ms260 is...

[computeruser]

Which iteration of the 026/260 produces the most power, has best throttle response, etc.? I know there were a few cylinders used over the years and a few carbs...I’m thinking I might want to add one to my 50cc collection and want to get it right. Would be wearing a 13”bar and .325”, if that makes a difference.

13” or 18” bar??

13"! All my 50cc machines run them. 13" 8t on a ported 50cc makes for a fun scalpel of a saw.

I guess it would be the 44.7mm piston with the adjustable oiler everyone is so fond of.

For what your running, any 026 will do.

If you want more power, do a muffler mod, port work, advance timing and adjust squash to .020. Also get an adjustable carb.

Really no need to hunt down a “perfect” 026/260 when they are easy to build out of any carcass.

My favorite stock cylinder is the early red lever non decomp KS round combustion chamber one but all of them can be made to spew wood chips with some port work.

The best stock runners are the old “red lever” saws. The late MS260 are smoother feeling to me for some reason, but not as quick.

My favorite modded jug is the late model 44.7 without decomp.

I always heard the red lever stihl saws were the best runners. Never any proof on my own though. But figure it had something to do with the stock cylinder porting that was on the saws at the time.

Sort of like I found out on the 262's. stock later mahle cylinder ones to me was oh hum nothing special. But the early 1990 with K&S cylinder opened my eyes.

Got a pretty red lever in the works! Thanks for the input, guys!

That is a nice one I seen too. Same one on oppie?

I've got three of the original 026's.

I run 16" bars on them with 3/8 RS chain.

I only wish that oiling would stop at idle but it is not a big deal either way.

Yup. Seemed like a clean example. I think it will do well for me, for those occasional instances when I want to put the 346s down.

Huh.....

As far as bone stock factory saws, the older 026. They came stock with several different carbs. The ones with the Walbro wt194 are best in my opinion. The 194 is the largest of all the carbs they used from the factory. Also like the sprocket ran oil pump.
