Hey everybody! I got a 6hp mercury 4 stroke
that's about a 2008ish. It's idling high with the idle screw backed off all the way, lacking power and pulsing if that makes sense. Last week I took the carb apart and cleaned it, float and needle valve appear to be working normally. Cleaned out the gas tank and filled with brand new Pemex Magna. I don't think they're adding ethanol here, at least I've never smelled it. So what gives? I've never had this much trouble getting this little motor
to do what it's supposed to.
