i took to lake yesterday and it would bearly move, rode around lake at like 5 mph for bout an hour at this speed. started back to hill and it started to spit and sputter like it wanted to open up but never would. Stayed on hill for bout an hour or so and went back out and it opened up for bout 20 seconds and died back down and steady did same thing til it finally died, now cranks for bout 2 seconds. any suggestions
