I have a gy6 engine 150cc gokart
It used to run trying to diagnose
Currently has spark.
And cranks but won’t start
I think the setup is all wrong based on what I have researched

The hose from the gearbox is connected to nothing?
I think this should be connected to the nipple on top of engine?
Which is currently connected to the air filter?

the hoses your talking about are correct. The hose from the gear box is just a vent no pressure or suction. The engine nipple is connected to the air box. That is the crankcase vent and should be connected to the air box.

When was the last time it ran? How old is the the fuel in the tank? Did you top it off or just put some in?

Last time it ran was April this year.
Emptied the fuel tank and put clean fuel in

Corrected the fuel filter flow direction

Found the fuel over flow connected to the intake manifold? Not sure if that’s correct

Check for spark ( good)

Still won’t start?

fuel overflow? do you mean the vacuum fuel petcock? is this a gravity tank? if so there is a hose going to the fuel filter, and a vacuum line that goes to the intake that opens the valve.
