I have 2 old engines, I mean really old, 20 to 25 years old. One is a OS 40SR and the other a magnum
40. I have no paper work and need to know a general procedure of setting the main needle valve
in order to get the engines to start or at least get a few pops. Approx. how many turns out should I use after I have turned the needle all the way in? Also when I am facing the front of the engine does the prop turn clockwise when running? The reason is that I tried to start one and the elec. starter was turning counterclockwise and the prop came loose,even after I felt I had really torked the nut tight. I can use any help out there.

Thanks, Jim
