I have an echo 602vl. I had it running great for about a year, then let it sit for a while. Went to start it, and it was air locked. I pull on the rope, but the engine barely gives. When I remove the spark plug, it spins freely. I had a lawnmower do the same thing and i adjusted the valve lash, and that fixed it. Is this the same issue, how do i fix this?
Thank you in advance.
