Travis, 

The carburetor does not have an overflow port.  So when the carb fills up, it flow into the engine cylinder.

The problem was gas in the crankcase.  Carb had to be replaced due to the seat at the float needle was letting fuel enter engine chamber.

I was riding my 610 when a huge cloud of white smoke came out of the exhaust.  I lost power, I stopped, the engine came back like normal.  I started back to the house, it happened again just for a second.  I shut it down.  Does anyone have a clue what it might be?
