seems to me most eddies have this kind of leak down. they will perk the fuel if the carb does not stay cool.

I use a 1" stacked plate/gasket 4 hole heat disapator under mine that made 90% of the trouble go away.

after a 40 mile ride you cant touch the intake but the carb stays luke warm to the touch. may want to see if yours is heat soaking after a run also.

heat soak when it is shut down evaping most of the fuel in the bowl then after a day or so the rest evaps out the vent.

does it have any bubbles in the filter when running? a sure sign it is sucking air.

look for dampness around the fuel pump weep hole on top,that will let it drain down to the fuel level in the tank.

it wont siphin fuel from the carb so it may be perking the fuel into fumes.

good luck,post back what you find.
