Fuel Problems????

On a hot day mine would drain back AND the Eddie carb would evaporate empty.
Used to bug the crap outta me to crank it untill it got the fuel levels back up again.

Swapped out to an electric pump, and problem gone.
Also if you end up running out of gas ever, you don't have to crank the crap out of it to get fuel to the carb again.

To answer your question, yes the factory stuff does that.
