My 12.8:1 stock stroke deal was wired to the stock starter with a 7AL2 in it former life. When warm, crack throttle a hair and hit key and it fired no problem. If you didn't crack the throttle the engine would go a revolution or two and then fire.

On the other hand if you lock out the timing it would make sense to crank and then fire i.e. with a crank trigger. Chances are if you have a crank trigger you also have some electronic capable of controlling timing to some degree. If not you can find an old school MSD 3 step timing retard box for reasonable money. Definitely verify the actual number if you use one damhik.
