16” or 18” bar more reasonable on MS261c when converting to 3/8” chain?

[MarkinGA]

So have a new MS261c and was planning to convert it to 3/8” 0.050” to match all my other chains. It will serve as an understudy to my MS462c which is wearing a TsuMura 28” light bar.

Was planning to grab either a 16” or an 18” TsuMura light bar for the 261c. Just not sure which is a more practical fit for that saw and 3/8” chain?

Either will be fine. I'm running a 25" 3/8" 0.63 bar on my ported 026. Less bending over, better reach for limbing, pretty horsey saw. I wouldn't do too much with the bar buried on mine, but you would use the MS462c for that kind of cutting. I pick another saw for that size wood, too.

This is a stock saw just for clarity.

What size chains do you have? Because if you are buying all new chains just for the MS261, you might as well keep the stock setup.

I would be getting new chains to match whichever 3/8 TsuMura light bar I get for the 261. My existing chains are all 20” and 28” 3/8” for my 462c.

Yep, I agree

I have a 261 that I tried putting a full size 3/8th .050, 20" bar and chain on it. It was a Stihl Rollamatic bar and a full chisel non skip chain.

It ran it so - so. It just didn't have the power to get all that wood out of the kerf and still keep the rpms up.

I was running a 7 tooth drive sproket.

I normaly run the .325 .063 bar and chain. 20" bar and 7 tooth drive sproket.

The 7 tooth .325 drive sproket is a good bit smaller than the 7 tooth 3/8th sproket, even though its still a 7 tooth both sizes, the 3/8th has a longer pitch and so therefore the circumference is obviously more.

With the 3/8 versus the .325 it was almost like two steps bigger: bigger chain and bigger drive sproket

I also tried Stihls "light" 3/8th .050 on the 261. It had plenty of power to run it, but I was having trouble with it having cutting issues when it was sharpened halfway. It would bind in the cut. Almost like the cutters were getting too narrow and not creating a big enough kerf for the bar to slide through.

My two cents.....................
