This sounds like the float is sticking in the carb causing it to flood . You need to take the carb off and clean it and put a kit in adjusting the float per the instructions

I have a walbro carberator that squits gas out of a little hole on the side near the top of the carb why?at the top why?

Probably the needle valve is sticking, letting the float bowl over flow. Remove the float bowl, and blow very low air pressure (less than 5 psi) through the fuel line. lift the float and see if the air blows past the needle and seat. If it does check the needle and seat. Sometimes a deteriorated fuel line will cause little bits of rubber to keep the needle valvefrom closing. If raising the float does shut off the air flow remove the float and check it.Brass floats on old carburetors can develop pin holes allowing fuel to enter the float causing it to drop. This keeps the float valve open. Some non metalic floats can become fuel soaking causing the same problem.

I have 1981 Honda CX500C motorcycle. You know the overflow hose that runs out the bottom of the carb back behind the engine by the center stand. Well the other day I noticed gas pouring out of that hose...

The carburetor over flow tubes should be open. Here are the possibilities. 1)Your carburetors are dirty and need to be cleaned. Clean your carburetors. 2)Your carburetor float needles are damaged and causing the carburetors to over flow. Replace your float needles. 3) The fuel filter is missing on the fuel petcock and rust is causing the carburetors to overflow gas. Put the fuel filter back over the carburetor inlet tube and/or add an inline filter to stop the rust from sticking the needles open and over flowing the carburetors. 4) Your floats have become saturated with fuel and no longer float in gasoline. Replace your floats. Poor idling or idling on only one cylinder can be caused by a bad spark plug cap. If you unscrew the spark plug caps and OHM them out they should read 5000 OHMS no higher and no lower. Good luck you have your homework.

Gas coming out of breather tube for rocker arm cover

Did you clean the needle valve/seat ?
Sounds like the float is not closing off the gas flow.
Could also be the float has a hole in it that let gas into the air chamber of the float. Be worth checking.
Pull the float and put it into hot water. If air bubbles come out the float has a hole.

Carberator gas bowl drain tube leaks gas. Screw is tight. Sorry I couldn't find an atv category.

The float is stuck open. Remove the carb, remove the bowl then clean the carb with spray carb cleaner.

110cc pocket bike carberator

That tube would be the overflow tube. Your carb float is sticking open and allowing fuel to flow in constantly. You need to take carb apart, clean needle valve, and inspect or replace carb float.

The carberator is causing gas wash on cylinders

Yes it is either the float is sticking or the float lever is set to low so as not to shut off the gas. Hope this helps. donnyb60
