On 2 occasions our Tohatsu has stalled after running for approx 20min. The priming bulb has been empty and we have had to keep squeezing the bulb to keep us moving. I thought it would be something like a blockage in the line or the valve in the fuel tank cap hasn't been opened. When checked the valve has been loose. Not as loose as when first opened, but loose enough. I will check for a blockage later this week.
Is there anything else I should check while I have it off the boat?
Cheers
