    Carburetor question Stihl MS-250

    I acquired a Stihl MS-250 recently that was missing the air filter cover. I got it to run with some fuel mix poured in the carb throat. When I started looking into it closely, the carburetor is mounted so closely to the cylinder that the front adjustment screw is completely covered by the...

    Echo CS-600P: Where does this part go?

    I am rebuilding an Echo CS-600P, and can’t remember where this part was located. I see it in the IPL, but it isn’t clear where it is supposed to be placed. I had some issues with getting the correct crankshaft bearings for the saw, so that has resulted in having been about 2 months since I took...

    Echo CS-600P crankshaft bearing confusion

    I have an Echo CS-600P that I am currently repairing and there is some confusion somewhere on the crankshaft bearings. I just removed the old bearings, and was ready to install new ones, and I noticed the outer diameter is different. The new bearings are too small to fit in the crankcase half...

    For sale is a Husqvarna 359 chainsaw. The saw is overall in good condition, has spark & compression, but I believe needs some carb work to run well.

    Should I replace this sprocket?

    I have an Echo CS-370 saw that I bought used, and I've read what seems to be a variety of opinions on when to replace the drive sprocket. It seems that the manufacturer websites say after you wear out 2-3 chains, the sprocket should be replaced. I have also read that ~0.5mm wear on a sprocket...
