Okay so I have some sort of results from my primitive testing. I installed a new ignition cap and carb. left the extreme flight flowmaster filter in the tank. so that didnt change. I choked the engine, flipped and flipped and flipped (did I say flipped??). No fuel getting picked into the line at all. SO I plugged the vent line with my finger, and blew through the filler line, zero sign of fuel trying to get through to the carb - I then let go with my finger to depressurize... okay. I took the old fortitude clunk and put it in the tank. within five flips I saw fuel working its way in. SO there you have it. For some reason this DLE35 does not like to suck fuel through that Flowmaster clunk. Blowing through the flowmaster and the fourtitude - fourtitude did indeed have less resistance. I tuned the plane with the cowl off, started putting the cowl on and it started to rain.... sigh. But at least I figured something out!!! I am kind of surprised there are very few reports of this happening to other folks.
I use Fortitude style clunks in all my tanks. Never an issue. Luckily the local hardware store stocks them at $2.00 bucks a pop. Apparently they use them in chainsaws or something.
