    I have memories of a husqvarna 420 that I had for a few summers in my youth.

    I just may do that. I have to take the 254 to the saw shop. I going to look at Echoes. If cheap enough I will have one.

    Be mindful of what the saw shop does to the 254. Many of them will tell you it’s scored and not worth fixing. If that happens just get it to the Michigan crew and have them forward it to me and I’ll get it going for you

    Took the saw to the saw shop. Ended up just being flooded badly. I don't understand. I had the plug out for 2 days. I figured the excess gas would have evaporated.
    I hate going to the "Saws-R-Us" store. Came home with an Echo CS-310. Nice light saw. Now if it holds up.

    Must have been a bunch of raw gas down in the crankcase...under the piston...it won't evaporate readily...take the plug out, make sure the ignition is off, then pull it over a few times until it stops spraying gas out...put plug back in and try to start it with no choke first, with wide open throttle if you can do it...if no pop, then try a lil choke. Not specific to that saw, more of a general procedure for badly flooded small engines...if it was a 4 stroke I'd say to make sure the crankcase doesn't smell of gas too (gas in oil) and that the air filter is dry (not gas soaked)

    To improve your chances with the MS250, and all Stihl's actually, make sure it has TWO starter pawls installed and not just one. The double-sided clip and pawls are cheap to buy. If the rotor is in good shape, you can keep it but any wear to the pawls, or rotor bores, will make it harder to start and feel like it's binding or jerking. Fresh starter parts, dual pawls, and an ElastoStart handle will go a long ways in improving the starter feel.
