I think I am going to touch up the Kadet with a fine stone and see if I can loosen it slightly.
Sootch00 has a great video on the Kadet on YouTube BoogieMan, he goes into fine details of the areas that he touched up to get a better fit to the SP01 frame. You might find it useful, I believe this is the video https://www.youtube.com/watch?v=J5ynDvroS7c
I hope you get to the bottom of the reliability issues soon!
