I found some cracks/melting on my 1995 Evinrude 9.9 E10RELEO powerpack, so I replaced it, along with a new impeller, head gasket, thermostat, and some other parts due to cooling issues. Anyway, now the boat is idling good and seems to run awesome, but it is idling so fast that the prop even spins in neutral when it's in the water. At first I thought I had adjusted my shift linkage wrong, but it shifts into drive and reverse fine. When in neutral I can pull the pull starter and the prop doesn't spin, but once it's fired up it slowly spins up to speed where it's really spinning fast. It's at what I estimate is maybe 33% throttle or something just sitting at idle. I think maybe the idle speed was adjusted before when the powerpack was failing just to keep the motor running, and now I need to adjust it to slow it down some. Do I use the screw on the starboard side of the carb (the one with the spring around the screw) or do I adjust by sticking a screwdriver through the air intake baffle, where the round wheel meets up with the ring below the flywheel?
