Hey Friend,
I tried the "extra" glow time. No real results on my stone cold engine. One obstacle that may have hindered the success of the "extra" glow time was that I forgot to hook up the idle cable after doing the valve adjust. She wouldn't start so I kept cranking, and cranking, and cranking. I almost had her going and then realized that the cable was not connected. After I connected the cable she fired up! I will try a cold start in the morning and maybe, with the idle cable functioning properly, she will start somewhat easier.
