The TC4's will always seem tighter compared to a belt drive car, i'm guessing that the pinion might be too tight.
You should be able to rock the pinion slightly without moving the spur, try this on several different places as you might find a tight spot.
Another way to find the right mesh is to use a cigarete paper between the pinion and spur.
