I did a search and did not find anything specific to this topic.
So Im going to ask the question, are any of you that use a needle valve water drip having inconsistency issues?
I have tried a couple different valves and have had the same issue. I set it, generator runs great!! Then generator not running so great. Check water drip, ah ha!! bone dry, open it up some more. Generator runs great again and then not so great and reset the water drip again.
Im not sure what the physics is behind this, but Im thinking all that is needed is a slight amount of pressure in the tank or a pulsing pressure. A very simple way to do that is to use a pcv valve inline from the carburetor to the tank. I am going to try this first, if that dont work I have a small diaphragm fuel pump with bypass but using it pump air. Ill use the engine pulse to drive it and hopefully it will produce enough pressure in the tank to overcome this obstacle. If that dont work then Ill use it to drive the water out of the tank into the valve. The bypass will then just dump back to tank just the same as if it was set up to pump fuel.
Curious to know if others are encountering this and what was done to combat this issue.
