Continuity mistake: When the gang make a second visit to the waste ground to test the go kart's new engine, Patchy is wearing a light coloured skirt, a button through front jumper and shoes. She is also carrying a small bag. In the next shot she is wearing a different skirt with pockets on the front, a different jumper with no buttons on and boots, and the bag she was carrying has also gone. In the last shot of this scene she is back to the clothes she was wearing at the start. (00:19:35 - 00:21:40)
Continuity mistake: In the first scene when Jimpy is riding the go kart down the hill he passes a parked Morris Oxford with nothing parked in front of it. After the go kart crashes into the lamp post the rest of the gang run down to Jimpy and there is now a Thames van parked in front of the Morris. (01:28:00 - 01:50:00)
