I have a U-Can-Do 60 size with a thunder tiger 91 4-stroke inverted on it. How do I stop this thing from flooding the engine? Do I have to figure out a way to lower the tank or is there some sort of valve that I can put on it? I'm looking for a cheap fix for this problem this is my second U-Can-Do. The first one had some issues with gravity.


Thanks for the help

Do you mean it's flooding between the time you fill the tank and the time you start it?

If you have an inverted 4 stroke and use a "T" to fuel the engine then you will flood it all the time because the carb is upside down and the flow of fuel will go into the tank as well as the carb when you are refueling the plane. If you can put a line from the vent to the tank and make your fueling system a closed system, then fuel will be drawn into the tank and air back into the fuel jug so that very little fuel will end up in the engine during refueling.

It floods between the time I fuel it and the time I start the engine. I am using a great planes easy fueler.
