Sorry for being a real noob but I'm still confused by what you mean "flipping the tube over". I just want to clarify what you mean.
The tube that I have, on one side it has got writing and an arrow indication. The other side is blank.
At the moment I have the tube with writing and arrow indication on the left-hand side of the car (this side of the tube is inserted through the plastic 38T pulley). The arrow is rotating in an anti-clockwise direction (or pointing towards the back of the car). If I flip the tube over, the writing with the arrow indication will be on the right-hand side of car (the arrow will still rotate anti-clockwise but points towards the front of the car).
Is this what you mean by flipping the tube over?
Really appreciate the help and sorry for being a real noob!
