just started sled for first time of season. had to pull over 10 to 15 times before it would start. several times almost felt like hydrostatic lock?? finally started and sounded like one cylinder, but then ran fine. smoke a lot, but brought up to temp and seemed to be running fine. shut off and had maybe 1/2 cup to 1 cup of black oil coming out pipe. tried to lite to see if raw fuel and it wasn't. 2014 pro w/ 600 miles. any ideas?? thanks
