Quoting Hertz:
My preferred method, line it up, put it in, try to start. If it won't kick over or stay running, take it out, turn the ear 180 deg and reinstall. Done. /ubbthreads/images/graemlins/smile.gif
Although they need to be instaled correctly, I have run them both ways myself and never noticed them wanting to stall. However, that has only been on stock motors. It is one of the first things I check when I get a new car to work on though, because 1/2 the time they are on backwards. /ubbthreads/images/graemlins/smile.gif
