One quirk I've discovered with the chain tightener, is that tension tends to change once the chain starts moving a bit. It's true that the teeth should not be able to escape from the bar, but unless you pull the chain around a couple times, the tension you're checking might be off. I think yours got tighter after you pulled it. Probably something to do with the sprocket. My rule of thumb is to make it as tight as I can while still being able to run it easily by hand.
For some reason, I have never gotten along with 45 cc saws. The MS 250 and 251 both give me problems getting them started. I got my MS 251 out of storage over the weekend and could not get it going. Pulling it over was like pulling an MS 880 without a deco valve. I thought it might be me but a younger friend could not get it started, either and he complained about the compression, too. I had run the 251 out of gas last fall and had not used it since last fall. I have not heard it make a whimper, since, so I checked it for spark and it has good spark. I also replaced the fuel filter and spark plug. All of my other saws came out of storage condition fine. I ended up doing some cutting with my ms 241 CM.
@@gunnadoofarm5109 it is running, now. It had what I refer to as ring lock or cylinder lock. Oil in a cylinder over time will solidify around the rings and increase compression so much you cannot pull it over. Get it running and the oil will burn off and problem evaporates. I got it running, yesterday and it is cranking like it used to. Red Armor leaves more oil in the engine than other two cycle oils, Like Stihl Ultra. Ultra used to puke oil all out the muffler, instead of leaving it in the engine where it belongs. Red Armor does not do that. Next fall,I may put the saw to bed with Moto Mix. My 181 CBE had the same problem after being in storage condition for seven months but it’s Easy Start feature overcame the problem. It was still harder to pull over than normal or now, after I got it running and did some cutting with it.
@@gunnadoofarm5109 I can understand that. I ran Stihl Ultra for years until it completely blocked the spark arrestor on my ms 241 C-M. I had no problem with it until then. However Ultra is filthy oil. Red Armor is so much cleaner. I don’t care about the smoke part of it. I just want good lubrication and a clean saw.
@@johnclarke6647 I use Aspen 2 fuel with mine, costs a bit but I've never had issues bringing it out of storage. Muffler looks pretty clean too. Maybe something to try I guess, if it's available where you are.
Novice saw user here. Seems like the saw dust was rather “dusty,” vice chips. Could the rakers need to be filed down a bit more? Seemed that the chain wasn’t “biting” into the wood very well.
I've had mine for almost a month. I've ran at least 8+ tanks at this point. No complaints. Easy too start and maintain. I have somehow worn down The bar a bit right before the tip. I think I had it too tight for the first tank or 2?
I like the 025 and 250 better than the 251. These are good little saws. It has a clamshell engine. Who cares, it will cut all day for about $200 less than the "pro" 261.
My bad, I didn't realize all the changes between the 250c which I have and the 251. It appears that the 251 is a cheaper version of the 261 which I also have. I have spent a lot of time lasteky with my 250c. It is pretty much at it's likit when cutting 18"-20" ash of which I have quite a few dead right now. The 261 chews right through these but my 250 had to work a bit harder. When cutting limbs or such that is say 8-10" it chews right through these
@@gunnadoofarm5109 261 is a totally different chainsaw! Is a pro level saw with magnesium housing and other pro features! Only similarity with the 251 is the brand and the color! Nice video but your chain is not cutting and also you tighten the chain too much! You mention that your sprocket need replacement🤔 sprockets last for thousands or working hours not only 20 😅

Yep, the sprocket needs replacing.
Very thorough overview 👏🏻👏🏻👏🏻. Thanks for sharing 👍🏻
No problem, glad you liked it

Take it to your dealer for a service so you can get it working again, you won't be disappointed

@@johnclarke6647 thats awesome l, glad you got it up and running, I am not aware of red armour, I only use stihl oil

Yep, you are right

Do you rotate your bar? Should look at rotating the bar every time you sharpen the chain.
I need one!
They can be bought at all good hardware stores
ive got a 250 and it has done its job.but then again i fix them
They are a great middle ground saw
Should we Tighten the chain after it gets loose Running minute or Two due to Heat? Or let it run loose
let it run loose after it heats up, otherwise you will wear out your sprocket on the end of the bar
Good ta see a Stringybark cut demo instead of all these pine/birch cuts...
Thanks Erica cat, there are alot of videos from america and Europe showing it slicing through soft woods, not many showing hard wood cutting
Thanks, very helpful vid ✅✅
Glad you enjoyed it

Can't say I have used either of those models, but the 251 is great for me and cutting firewood
thanks share this video
Glad you liked it
Are you sure that's a 251. I have a 250 and 261 that saw looks more like my 261 with top cover, air filter and such. I cannot see closer on my phone

Yeah it is a 251, I havent used a 250 before but I assume it is similar to the 261 with a little less performance
