I am trying to set the timing on my 93 sedan and all I see with my timing light is a thin line then several dots above it going towards the passenger's side. This does not match the Fox Bentley's description nor any other Bentley that I have. There are no numbers to be seen. How do I set the timing? Which dot is right? My car is pinging under hard acceleration and I'd like to get her running smooth. Any help would be appreciated.
