Hi twinboss2,
Set the plugs at .035 (AC-46-5), The points at .022 and while your are at it set the valves at I=.006H and E=.013H. If it is a PG engine=don't touch the valve adjustment. Set the timing to the steel ball in the flywheel. Idle speed 475 except PG is 425. Air adjust on carburetor set to max RPM or better yet, max vacuum.
