Yea, it's possible the spur is warped, but it's hard to tell by eyeballing it. It seems like everything rotates well until I add the goofy spacer and spring.
I did have to replace the original spacer as I accidentally broke it by overtightening (I got a little carried away with my slipper tightening hehe). The replacement spacer part is for the Losi Hydra drive and looks identical to the original in size and shape.
When I eyeball the replacement spacer I don't see that the size contacting the slipper shoe is perfectly flat. Spinning the assembly makes the replacement spacer look out of round (wobbles) as it spins. I bought another spacer to see if I got a bad one but they appear the same.
Maybe I am being just too crazy with this wobble thing. It bugs me and I want the car to perform well.
To answer the above question I missed. It is a small wobble about 1/4th the width of the spur gear.
Thanks for the advice guys.
