Jerky Pull Cord

[Okie]

I haven't had a chance to tear into my saw yet, but NEW, dosen't necessarily mean it's assembled or designed right.

I now see that you are not the Original poster.

You might get new info if you will start a NEW post. I just happened to be subbed to the old post.

You were told how to start it. Common issue an most every MS250. Start with the piston too low and it will jerk it out of your hand. Is it timing, is it compression, is it the recoil design. Could be all of the above. No cures. Start it with the piston near top and pull it like you mean it.
Not a saw for the weal and slow of arm.
Get an easy start.
Now, can we get back to oil
