Hi, Old Gas, I've been working on a very rough 100a pump. I am having problems with the large center hose retractor. I took it completely apart and thought I had all parts free and moving properly. I have the mechanism pivoting out correctly but am unable to get the hose to pull out more than a foot before it locks. Looking at the upper locking piece with the large hole in the center, I am wondering if that piece should turn, it seems to be impeding the release of the hose. Any suggestions would be appreciated. Thanks, Ron
