I have a TEC H60 with a cast aluminum recoil. After I reassembled the recoil and pull the cord it all works perfectly. I mount it on my motor, give it one pull it works perfectly, when I go for the second pull....nothing...the dog stops coming out. When I take it apart the center screw has backed out about 1/4 turn causing this. Any ideas?? I have no idea if I am missing a piece.
