Good job Jim .... that's definitely running slower. I've got mine down a bit slower than that by slightly stretching the original springs. But of course I did actually overstretch them, so have to mount them in an arch now to take up a bit of the excess slack that I shouldn't have put in, in the first place.

You are definitely on the right path. You might want to consider trying slight adjustments with the timing too, but be sure to carefully mark where it is now so you can always get back to "ground zero" that does seem to work pretty well.
