I have a MS251C Saw and it has a damaged piston and Cylinder from an initial inspection. I have been informed that the cylinders available fit the MS251 and Not the MS251C. How do I make sure that the cylinder I buy will be the correct one. Thanks for any information. Bob, In Australia

Simple. Bring the saw to your dealer and let it fix there.
Not helpful if I'm doing the repair myself, thanks

I thought the only substantive difference between the regular saw (any model) and its counterpart w/ the 'C' was the recoil mechanism. The 'c' variant simply has a spring and a ratchet - pull the cord to wind up the spring and store energy, and when the spring's power overcomes the compression, it gives the crankshaft a push like an energetic pull on the cord.
I'm no expert, nor have I taken one of these apart, but when I bought my MS250c, the salesman told me what I described above. I'm interested to learn if he was mistaken and if there in fact, is a significant difference between the two models.

Yes, as far as I can tell, the only difference, as you stated, is the recoil mechanism. I have an MS250C apart right now and it looks like an MS250 although I have not checked the part numbers. I need to replace the case because the lame dealer did not assemble it correctly, or it was boogered at the factory. The clutch & sprocket were not mounted right and it ate the oil pump drive and the case!
Apparently there are 2 Two types of cylinders for this model,s , I'm talking After market and not OEM here, Too darn expensive to put OEM in, when another will do. The 251C also has an external pump plunger to pump fuel into the carb. I have not pulled it apart to check measurements as yet, but the brake band is also a different setup. One of the dealers here states that the cylinders he has (aftemarket) are different to the 251. Thanks for the response
MS211c, MS250c, MS251c, all require a different flywheel.
Go over to the beg for manuals thread and request A IPL. Should give you proper part numbers for you saw.
You need to look this up by serial number. 3 part numbers shown. Seem to fit CB or Z.
That makes sense, but I was suprised to hear they use different cylinders. Not sure why that would be. The one I have open looks the same as a non-C version. But, I don't have them side by side and it has been a while since I saw the inside of a non-C 250.
