Long story.
When I built the kit I used it.
First race I had issues that sounded like loose pinion.
Guy and the track took the motor out for me and reinstalled the pinion using the guide.
Still didn't work, made weird sounds and had no drive.
If turned out that even using the guide it wasn't mating up properly.
I installed the pinion on the shaft with the gearbox apart so I could get it to exactly where it needed to be.
I'd done this a little wonky (it is right on the end of the shaft) so moved it down a mm and straightened it up.
