I have a 99 Vmax and it starts fine but will not keep running unless I bump the choke. This is the case at any throttle setting. An external visual of the fuel filter, it looks fine (but am not sure). Ran fine for a couple of days when put it in the water after winter but then started acting up. Pumping the fuel ball doesn't change anything. Is on a Hurricane with 25 gallon tank that was filled after taking out of storage. Thanks!
