My U17 will absolutely will not start unless plugged in for 10 minutes or so. it gives off white smoke out the exhaust pipe and I can smell fuel when cold. After plugging in the block heater it starts just perfect. Ive got less than 100 hrs on her. and its off warranty. I spoke with the dealer and he says to bring it for service of course but right now I'm 500 or so miles away from the nearest dealer. Any suggestions what I can do out here in the middle of no where?
