Motor spits sputters for a few minutes then takes off
Older yamaha gas golf cart spits and sputters for a few minutes then will take off.
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.
use premium fuel and don’t leave cart half empty. Always keep topped up
Had same problem, and slowly went to a no start at all, new carb got it running. Checked fuel pump, adjusted valves, brand new coil and plug.
with new carb it still does it. I agree with water in fuel. I also put product in and it helped for a bit, guessing the product is heavier than gas as well as water. Drain and use non ethanol, maybe some sea foam? That’s my next move.
