IT is likely that the carb is leaking fuel and filling the crankcase with fuel. Causing excessive crankcase pressure forcing oil into airbox through the crankcase vent. Check your crankcase for fuel and/ or being overfilled. If fuel is present fix the carb first, then drain and refill crankcase. After all is fixed run the unit outside for a few minutes and let it burn off excess smoke.
