I just compeleted a carb rebuild and replaced the starter assemby (PITA first time but I think I got it down now). Problem is with the red interlock dog. It seems to move at will with no rhyme or reason sometimes preventing me from pulling the rope. I have to manually push it out of the way to crank the engine. It is behind the starter cup bar in the correct position from what I can tell. However there is small 1inch spring that protrudes off the dog and I'm wondering if this spring is supposed to attach to something. I don't see anywhere for it to attach and don't remember it attaching to anything when I disassembled the starter. Thanks for your help!!
