If the generator is not running, it is possible that the line from the shut-off looses the propane to someplace. Then if you try to restart, the line from the valve to the carb (or injector) is full of air and needs to wait until the line is filled with propane.
Well I left main gas valve open then it starts EVERY TIME!!! When I close the valve for about 30 min, open valve and try to start immediately, it won't start. I wait for another 30min while the valve is open then it starts right up. I think gas delivery might not be at its best. Anyone has any explanation for this behavior?
As you describe your routine above, what happens if you open the valve and wait for those 30 minutes - does the generator then start right up? Sounds like the line fills with air and it takes a while for the air to be purged out.
My gasoline lawn mower acts the same way. If I close the valve under the gas tank, the next time I try to start the mower; I have to wait until the gasoline fills the carburetor. The gas evaporates from the carb between mowings.
