I use a piece of paper to get a good mesh, as I would do everytime, and it meshed properly. But eversince I use 22 and 23t 2nd pinion I always ended up with stripped gear. This usually happened after the 10 mins of using it. I usually set my car to engaged to 2nd gear at 1/3 of the straight. At the moment I m using 21t pinion and so far it doesn't strip the spur gear.
