Grinding sound

I have a Ms271 chainsaw and recently have replaced the bar, clutch and sprocket but when I go to run it, it feels like something is grabbing it because I don’t get full power and it has a grinding sound. After a bit started smoking a bit so I shut it down. Any thoughts where and what I look at next?

    Did you match the bar and sprocket to the chain gauge and pitch? A common mistake not to do this. A .063 gauge will not work in a .058 gauge bar nor will a .325 pitch work on a .375 pitch bar or vice versa.
     
    From there you need to check the crankshaft bearings. This provided that you didn't straight gassed the engine.

    So, if it’s the crankshaft bearing, how difficult would that be to fix? Or would it be advisable to take it into a shop. I’m not a mechanic but I can work on Stuff and figure it out. But if there’s too much to get into I don’t have the time, nor patience to mess with it.

    It is a bit of work, the saw needs to be stripped completely. You will need a puller to remove the bearing from the shaft and a way to heat the new bearing, warm oil works here. If you are not comfortable doing it yourself a competent dealer is your best bet but get a quote first, a new(er) saw might be a better bet.

    AVB, you are the man. Thank you so much for the advice. It was the bar and sprocket not matching the right gauge and pitch. I appreciate the advice, in which helped me immensely. Now I can get back to all the fun stuff now. Thanks again, much appreciated, amigo

    Thanks for letting us know. Too many times we never hear back so  there is no opportunity to learn from it.
