Recently purchased (unused for 3 years), had the carbs rebuilt at time of purchase, and new spark plugs installed, new water separator. Had 25 gallons of crappy fuel. Ran through most of it and put in premium (I know now that probably wasn't the best idea after reading some octane posts.) <br /><br />After 10 full day fishing trips (1-2 hours running) Engine has progressively been idling rougher, however on my last trip engine would often stall at idle. <br /><br />On the last trip, more often than not, when I made an attempt at throtling down... it stalled almost as if starving for fuel, however if I did get it going, it ran fine. <br /><br />Also... Last trip... The only way I could keep it going at an idle wasy by hitting the choke button every 5 seconds (otherwise it would stall).<br /><br />Any feedback or help would be greatly appreciated. Thanks.
