cumn thru.. what do you mean make sure the throttle is closed before backing out. Are you saying that in order to completely close the low end that the throttle has to be closed or it will not screw in all the way? I don't see how that would correlate.. so... I think I am just not understanding you.
c016Y, Not before backing out. When you are screwing it in, the throttle must be closed to find the true bottom. If the throttle is open the screw will go in further and not attain a correct setting when backed out 1 1/4 or 1 1/2 turns whichever your engine requires.
Nova, perhaps too lean. I get mine close to attain idle. at idle I adjust until the rpms raise and it smooths out. It always ends up dead on. Watch that prop! Joe
