Motor runs strong, always seems to start ok when cold. After starting and stoping several times, it becomes unstartable. I have disconnect fuel line at the carb to test fuel pump, it is pumping gas into carbs. I suspect that the choke valve is sticking, or that I have a float sticking. Spark is good, as I said motor runs strong. Where is the choke valve? How can I check it. It has three carbs, do they all need to be checked? Any tips on what to try first would be appreciated...Thanks
