The cars are back with me, so I have taken the time to check a couple of the cars today. Probably the rest over the next week or so.
In particular I ran the ALS Thunderslot Mclaren on my home track, the time was consistent, so moving the pinion along the armature seemed to have worked, but replaced it with the spare I ordered anyway. It fit much more tightly onto the armature so should be good for the rest of the series. The lap time was exactly the same as with the original fitted pinion, so sadly no big improvement in performance. However when I measure the original fitted pinion against the new spare it was 0.1mm bigger in diameter and 1mm shorter ? So I don't feel that the one fitted was actually a standard part although they are both 11 teeth.
I also tested my own Club set up Thunderslot Mclaren M6A which ran a 7.4 sec lap compared to ALS similar car of 7.8 sec, so there appears to be a significant difference in performance regardless of the pinion issue.

However ALS Camaro is still looking good, the new grub screw in the rear axle seems to be holding firm.

I will look over the rest of the cars before we run again on the 12th November.
