I have an O’Day 34 with an Edson mount which my throttle control lever is mounted to. The throttle control lever is covered with a red plastic like paint that is beginning to chip. I tried to remove the lever so I can repaint it but didn’t seem to want to budge. The lever has a set screw that I completely removed, however I still cannot remove the lever from the stem it’s mounted to. Does anyone know how to remove this lever? I don’t know if it has corroded onto the stem it’s mounted to or if there’s something else I need to loosen before getting the lever off.
