Ok so after receiving great advice from my “LT50 running hot and sluggish” post I decided to completely strip down the quad and investigate!

Ive replaced the piston, de carboned the head and exhaust port in the manifold, changed the oil and now I’m putting it back together!

The problems I have are

A) I can’t remember where all the fuel and oil lines go! Like an idiot I didn’t take photos!
B) I can’t work it out as after a bit of research I think someone had done half a job on trying to convert it to a pre mix fuel.

The Fuel **** had the vacuum line removed although it appears the diaphragm is still there and working.

Attached (I Hope) are some photos of the pet **** and main gearbox casing.

Picture one is the pet ****, I’m assuming the outlet without the line is the vacuum line, where does this connect to? Pic 3 show a line that has been capped off just after the Carb and before the manifold it this where it goes? (It’s my best guess)

The next issue I have is I would like to return it to factory and use the oil tank. I think the bottom line fits on the large inlet on top of the gear box but where does the top line from the oil tank go and what is it for?

Pic 4 show a small line attachment on the top of the gear box to the rear? I’ve no idea what this is for can any one shed any light and tell me where and what it connects to it had no pipe connected?

Lastly there is a small line attachment on the carb next to the fuel lin in, I assume that this is the breather line?

Any help would be greatly appreciated.

Thanks
