Jammed kickstarter

I recently rebuilt the engine on my SF ET3. Before closing the cases everything seemed to move and turn freely without any issues, however with the cases closed, the kickstarter won't move without great difficulty and doesn't spring back. Has anyone had this experience? Any thoughts on how to get it working properly?

I had exactly the same on my ET3 engine which had only been rebuilt a month or so previously. I opened the case up and found the kickstart quadrant shaft had a crack in it and was starting to bend. 

Kickstarter shaft must be bent or you have something assembled incorrectly.
