Because the tube (hose) is defective and needs to be replaced. That tube is coming directly from the fuel filter being pumped by the fuel pump to the carburetor. Replace the tube/hose or you WILL have a major engine fire and/or huge KABOOM.
No, get the floats re-adjusted in the carb.
you need to check the accerator pump. check for pin holes
your float is stuck in the carburetor. Clean it with carb cleaner.
Your carburetor is loading up. Or your needle valve is out of place or stuck.
The location of the fuel line depends on where the carburetor is mounted. If the carb is mounted directly on top of the fuel tank, the fuel "line" is the pickup tube that extends from the carburetor into the tank. The carburetor will have to be removed to get to the pickup tube. If the carb is mounted away from the fuel tank, the fuel line will come from the tank.
Yes
If it's coming out the overflow pipe, then it's likely to be a sticking float.
I need the information where to connect the Hydrogen Gas to the carburetor on what side
easily unattach the hose coming from the tank leading to the carburetor turn the gas ''on'' and drain and then turn to "reserve" and drain the rest of the gas.
Probably not the tank but the fill tube, or fuel lines coming from the fuel pump
Having water in the gas tank will work its way up to the carburetor.
The float bowl and the venturi tube
