Normally, I do not recommend dial back timing lights. They are usually not very accurate....that is unless you spend a lot of money on a digital one. BUT, you can get an old analog one cheap. Why? Because you can learn a lot from it. Play around with it and see how it works. That will tell you a lot about what's goin on right there. Then use a standard non dial back light to set timing.
