I think I could do with some more intial but I'm really not sure. See motor specs below and send some input my way.
If I have missed any info please let me know. Thanks in advance. (No pun inteded)

You definately need more initial. Limit the mechanical to keep the total from being too high.

More timing info here.

Good luck.
