The best solution for me is to simply do not not use a three line system. Cowling or not I always use a two line system just as on any trainer and always fuel toward the tank in the clunk carb line therefore flooding cannot occur.


Its very simple to loop the clunk to carb line out a slot or two holes in the cowl cutting the line there and inserting a 3/8 inch length of brass or alum tube. Very easy and fewer things to go wrong. I also use it for uncowled engine with rear neecle valves to simplyfy replacing that line behind the engine.

In the topside photo of the red/black Cap you can see the fill line that is just pulled up a little and fueled from there.

This method also provide the added benefit of makine pinch tuning possible, A method much preferred by me.
