Could be some water in the gas. Water is heavier than gas and goes to the bottom of the tank. If you cart sits for a while with gas in it it can loose some of its volatility. Airplanes have drain valves on the bottom of the wing tanks . When doing a pre-flight you use a glass or clear tube (looks like a pill bottle to press it up against that value to open it and the water contamination drains out. Usually you will get a couple of table spoons full. So when storing your cart for any length of time it is best to either run the tank dry or drain it. Same thing happens on lawn mowers, especially after sitting over winter time.
