Hello all. I fixed a broken string at the end on a Craftsman 5.5hp snowblower. I removed the cover, restrung the recoil mechanism and hooked it back up to the Snowblower. When I went to pull the string, there was no tension to make the string recoil. I took it off and hand wound the mechanism till I thought I had enough tension to make the string recoil. My question is there a certain amount of tension to put on the recoil mechanism? I gave it a few turns till I got some tension but didn't wind it too tight. The string broke again so when I replace the old string I want to make sure this time I rewind it with the proper tension. Any help would be appreciated. Thanks in advance.
