I was fishing a tournament the other day and motor ran like a top all day. no problems at all. right before weigh in a was leaving my spot and stomped on the gas peddle and the motor studdered and almost shut off. i sat the for a few seconds and let it idle and give it some gas to clear out the bad gas then stomped it again and it was fine. boy i wish they would just cut out the ethynol. i cant stand that stuff.
