What happens when Honda GL1000 carb hardens?
This false economy will likely doom you to misery. When the internal o-rings harden they also shrink. This can allow fuel to by-pass the jets and float valve seats. Needless to say, this leads to over-rich and flooding problems.
Can a CARB have both fuel and air screws?

What causes fuel starvation on a GL1000?
Fuel Starvation Possibilities (or sometimes dead cylinders that mimic an ignition problem): A blockage inside the fuel tank. Perhaps this has migrated also to the fuel inlet screens under the float valves. If you suspect a tank blockage, siphon most of the fuel from the tank and remove the petcock.
Where are the air jets on a Honda GL1000?
Primary and Secondary Air Jets. These are located under the kidney-shaped plate on the top of the carbs (under the cap). These sometimes develop a fungus-like coating on lightly used bikes that will cause all sorts of over-rich problems.

What causes gas to back up into the air box?
It just caused the gas to back up into the air box and leak from there. Perhaps you have a blocked drain and stuck needle. I have the same problem, all 4 carbs are leaking into the airbox. I rebuilt the carbs and checked the amount of gas in the float bowls and it’s not overflowing.
What causes the carburetor on a Rochester Monojet to flood?
The Autolite 4300 and Rochester Monojet is especially guilty of this happening because the float fills up the float bowl so much. The most common cause of flooding is dirt in the needle & seat. What happens often is you clean your carburetor, then start the engine.
Can a fuel pump cause a carburetor to flood?
The fuel pump is another possibility. If you have an electric pump be sure to have a regulator installed between the pump and the carburetor. Set it fo 4-5 lbs as per your motors manual. New fuel pumps are especially suspect. It isn’t unusual to have them pumping at 20 lbs of pressure.
