Adjust slow idle needle valve 1.25 to 1.5 turns from seated.
Where would I find this needle valve? Is that the one accessible fromt he outside of the carb, with the spring wound around the screw? Or is it the one up inside the carb that runs up the center of the body? Also, should I turn it clockwise or counter clockwise? Thanks.
I would add that you should adjust the idle mix with the ingine in gear--be in the middle of the lake or tied to a pier, or securely tied down on your trailer backed into the water. [links]

RPM Information: 4500-5500
Your engine's RPM range is important in choosing the right propeller for a given application. For example, if you look at your tachometer at top speed and it is not within the engine's RPM range then that is generally not good. You want your RPM's to be within the proper range while at wide open throttle (WOT). Be sure to do your testing under your normal boating conditions and with a good propeller (not bent, cracked, or excessively chipped).
