I have a searsgamfisher 1.75 or tanaka 175, the same motor, and after soaking the carb and scrubbing it clean, the motor still doesn't have a real low idle. I have with many other outboards made by merc, omc and the like and I can get them idle down real low. There is only 1 idle screw and that seems to limit how open/closed the throttle gets. I am wondering if this is normal for these motors? It starts and runs fine, and I figure a motor this small will spend most of it's life at WOT, but I sure wish I knew how to get it to idle down real low. Lastly, does anyone know the oil type for the lower unit? or have the operator manual. I have the parts diagram, but sure could use the manual.
thanks in advance.
