I have a 2003 BF15D that I recently brought out of winter storage. Cleaned carb thoroughly, cleaned and checked spark plugs for proper gap. Start and runs fine until it warms up to normal operating temp. then begins to sputter and cuts off at all throttle positions. Will run for a little bit at low idle after it cuts off. Checked fuel filter and there seems to be no blockage. I recently took into dealer for fuel chamber recall as well as accelerator pump cap service bulletin and I told them about the issue. The dealer performed the recall and service bulletin work but didnt test run the motor. So its my problem know since I don't plan to take it back given there piss poor service. Any suggestions would be helpful. I have new spark plugs and a fuel filter on order.
