[QUOTE="Jay415, post: 274620, member: 6905"] Just bought a 1999 2-stroke 25HP ELH Mercury motor. Run pretty good but I think it might need some carb work. I changed the plugs, cleaned the gas filter, and used fresh gas with ethanol treatment and mercury synthetic 2cycle oil, 50:1. Motor starts right up and seems to idle fine. It'll will putt along slowly so so, but once you give it gas to accelerate it want to stall. I have to play with the choke a little to get it to accelerate. Once I get passed that I can adjust throttle from 1/4 throttle to Wide open and back and forth with no problems or bogging. Once I slow to an idle and try to accelerate again it starts bogging. I though maybe the idle was too low so I turned the idle adjustment screw slightly but it sounds like its idling a little too fast and it hasn't helped, still the same bogging when accelerating. Plus now it's slamming into gear harder. The motor was very clean and sitting around for a while. Am I thinking right, that is must be a carb issue? What should I do to remedy this? [/QUOTE]
