I recently brought a 1993 Mariner 4/5hp and am having problems starting it from it's internal tank. It starts straight away from an external tank, and I'm guessing it's been used with this for many years.<br /><br />I've open the flow from the internal tank, there's no blockage from tank to cut off switch.<br /><br />After about 10 pulls with full choke the motor starts very smokely and then dies regardless of how much throttle I give it or when I put the choke in.<br /><br />Any ideas?
