New to the site but i am gonna give y'all a try //////// so here is what i got, just bought a new boat w/a 50 hp 2 stroke supposedly has under 20 hours on motor and he tells me only ever filled up it twice, it was in storage for a year don't think ever took it out once it got to the storage yard. anyway. tank was full when i got it treated with stabil marine and took it out, runs good at wot but does not idle and stalls at idle, I siphoned gas out and put 15 gallons of high Tess gas and treated gas w/ stabil-marine, took out again this morning and does the same thing, bought new plugs today thinking they might be bad, nah that wasn't it, looking for other options before i take her in the shop, thinking pulling the drain plugs out of the carbs and spraying carb cleaner in them really good, i don't know what else i can do i did have to pump up the bulb a couple of times after stalling on the water so might be some kind of restriction flow or something // engine looks really clean and new so that's why i am leaning towards the carb's
