Boat ran great in 2009. When I winterized last year I checked compression (110 in cylinders 2,3,4,5 but couldn't get to 1 or 6. Full tank of gas with stable and seafoam. Carbs fogged. Getting it ready this year it started and ran/idled fine with muffs. Put in new plugs with (gap double checked). I've run a few tanks of gas thru this year and noticed doesn't want to idle well and will stall. Runs great WOT and always starts. Just won't idle hot or cold. Will idle all day long with idle leaver up. I've read many post here so will a simple adjustment be in order or carbs cleaned? I plan to rebuild carbs end of this season, just hoping to get away with a simple adjustment till then.
