i am not sure how but i think my timing marker pointer thing whatever you call it is gone. is that the only place you can shine the light. after doing my intake swap i brought it to the mechanic to set the timing because 1, i did not have a timing light, 2, the car was way down on power so i knew the timing was off, 3, i am trying to learn how to use the timing i just bought. is there any place else to shine the light?
