I ran into some of the same troubles. Here's some facts I have learned:
First of all, Carreras can't run on Scalextric Classic track, but they do fine on Scalextric Sport, with certain exceptions.
The longest "keel" guides from Carrera will hang up in the tightest curves of most plastic track. Some folks cut a little off the front and back of a Carrera guide to help it get around the tightest curves.
The slot in a wood track can swell with moisture, making it narrower. If a router bit smaller than 1/8 was used to make the track, this can be critical. Just wrap some 100 grit sandpaper around a plastic spreader and put it in the slot. Then shove the sandpaper around the track until it goes around smoothly. Blow out the dust and try your car that had the most trouble. Chances are that alone will fix it.
When I have been at someone's track that is Scaley Classic, rather than miss out on a race, I have ground off just a little bit of the bottom of the guide on my Carreras, just sand it off full length of the guide until it no longer snags.
Of course, you can always simply replace the guide with an aftermarket guide and be done, once you solve the narrow slot problem on a wood track that has swelled.
