My Summer Car tractor bug -- all fuel is emptied

This happens when attempting to restart after it stalls (not sure why it's stalling). I verified that the tank is empty by using a fuel can, which shows a black bar.

before start the tractor you should throtle up (hand throtle)

A year ago it was not like that and rusko is getting worse
