Also believe 14mm if I remember right is the size of the head nuts. the size of socket needed for the gear is 19mm and be sure to turn clockwise and feed chain from the bottom.
Do not disassemble your engine unless you want to chance voiding your warranty. Most kit suppliers will not take the engine back if you have taken it apart. Many members have had trouble getting a new engine to move at first. Try moving the clutch lever inward as far as you can move it by hand. It takes a lot of force but it can be done. Wrap a rag around the clutch arm and apply a lot of pressure. Often the clutch pads will release by doing this. You will hear a 'thunk' sound when they let go. All new engines are a little tight. Give it a chance and only disassemble it if you can afford to buy a new one if your seller will not take it back.
