I'm hoping Mizkaki or Tammi show up around here. I've messed with that but I don't know how to tell you. Keep tinkering - I had one I worked on for a very long time - I had to walk away a lot - but I kept going back to it. Finally I took it all back apart and put it back together and got it timed some how and it worked just fine the 100th time must have been the charm. It would help to know what you are doing wouldn't it? I know the thing you are trying to work around - is there any adjustment in that? Is there something that holds things in place? Is there a screw you loosened and forgot about? When you put it back together, does it turn before you put it on the shaft? There is only one way that thing goes and if one little thing is wacky you have a problem but most of the time it simply won't assemble wrong. Worst of it is you don't have anything else just like it to look at... My problems were self inflicted, too. Take your time and if you have to go walk away. Tension Tamer tea...
