poor judgement

Thank you for the reply.

I should have said in the first post - The mesh isnt tight, its a bit slack to be honest but its as tight as the mounts will allow, the motor wont go any closer to the spur. Perhaps its just come with a particularly small pinion..?

I will count up the teeth on both gears and see what Ive got. Any ideas what the standard ones are so I have an idea of where Im at with those?

Sorry for the noobness.
