If it doesn't have a fuel pump but does a float bowl carb which is the only entry to the crankcase your float valve/valves aren't seating.

If you have a fuel pump which is crankcase pulse driven, your fuel pump diaphragm may have ruptured, allowing fuel to go directly from the tank into the crankcase.

Either condition would result in what you've described.

Hope this helps,
