I thought the pull start was frozen. Trying to pull enough cord out for it to snap back I broke it. I tried the electric starter and just got a buzz. We had a few freeze and thaw cycles with wind and rain so I figured It was frozen up as well. I moved it in doors. All warmed up same buzz from the electric starter. Removing the pull start and cover for repair I noticed the electric start gear is all the way out. I removed it as well but still can only turn the flywheel 1/4 turn to a clunk stop each way by hand. What could be jammed?
