    A full choke greatly increases the richness of the fuel mixture by changing the ratio of air to fuel, starves air. You should not run the engine on fuel choke because, although it may run, the chances that you have a good mixture or ratio is very very slim. You have a carb issue that needs fixing. Right now your carb is supplying not enough fuel so the normal mix of air is too much, chokes lowers the amount of air. In short, your carb is gummed up and needs cleaning.
