A couple of problems can cause this.
Turn the gas off and take the drain screw out. Look at the end, it should be a needle type valve. If the point is damaged or corroded, have it changed. Two dissimiliar metals combined with water collection in the bottom of the bowl causes this. It is good maintenence to drain the bowl every two or three tanks or at least quarterly.
Another, and the most common cause is the carb float is stuck in the up position. The carburetor needs to be cleaned if this is the case.
fuel leaking out drain hose while driving Honda z50
run the engine out of gas!
There should be a screw in the bottom of the float bowl on the carburators.
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.
Take the tank out of the ATV, invert it & drain through fill cap. Or, pull off valve, remove screen (just pull out with needle nose) & let drain.
Leaking windshield or clogged windshield cowl drain lines.
Can be a leaking heater core if the fluid taste sweet. Can also be the drain tube for the windshield cowl is stopped up.
open up the float bowl drain screw and don't forget the reservoir (bottle) under the drain tube below that the hose that connects to the petcock off the drain screw.
isnt that bike fuel injected The 1800 VTX is fuel injected, the manual for the 1300 VTX say drain carburator for winter. What I don't see is a drain screw of any type. DNUNN
Although I cannot be specific with this make and model, this trick has worked on numerous vehicles over the years. Disconnect the fuel line and unscrew the drain plug, which is located on the side or bottom of the carburetor bowl. Drain as much gas out as possible. Also drain and clean the fuel strainer and clean it with carburetor cleaner. Now either spray or pour carburetor cleaner into the fuel line and let it drain through the carburetor. At first it may not drain, but as it removes the varnish and gunk it should soon begin to flow. For really stubborn and a through cleaning of the carburetor you can replace the plug and fill the fuel line with cleaner and let it sit. I've done this in chainsaws, boats, bikes and cars over the years and have always fixed the problem.
If it is just water and not coolant, then suspect a leaking windshield, or possibly a A/C condenser drain line stopped up. If it is coolant, then the heater core is leaking and needs replacing.
Try cleaning out the drains on the corners and make sure the drain tubes are clear. Otherwise, replace the seals.
