There is something in the fuel line before the filter,,, it's either a small piece of plastic that lays flat for a while and then moves or someother flat debris that's acting like a flap valve

I still say it's crud in the tank. Seen this same problem a few times now and it's been a dirty tank every time.

The lines to the T connector with a cap on one end, that looks like one of the lines comes from the intake manifold, it should then attach to the fuel petcock. That vacuum line is what actuates the fuel petcock allowing fuel to flow through it. Is it hooked up?

It appears from the pictures that the fuel petcock was bypassed for a straight gravity feed system. The T on the vacuum line was capped with only the carburetor attached to the vacuum line.

It may be just the angle of the pictures, but are you sure you have a good slope on your fuel line? Again, it may be the angle of the photos but a few spots in the fuel line appears to run slightly upwards. That could explain why you are not getting enough fuel to the carburetor, and how blowing into the tank vent to force the fuel down fixes it.

The picture of the rear of the scooter with both shocks is a good example. The line from the tank on the left-side of the frame appears to have the fuel line just below where the spring starts. However on the right side of the frame, the fuel line is above the beginning of the spring.

The only thing I would check is if when sitting on it the fuel hose is getting pinched. I labeled where I would check if putting pressure down the hose is getting pinched. To check if any part of the fuel line is getting pinched or moved just grab both sides of the frame and put your weight on it and see when that part of the frame goes down does it mess with the fuel hose.
