Well.....there IS no stock plate. There's nothing in stock form to limit the total advance. I heard back from Don and this is the only plate they offer. I mean really, how hard would it be to make two? A low advance and the standard one. The standard one goes from zero to 18 in 2 degree increments. It shouldn't be too difficult to make one from zero to 12 beginning with 4. Evidently this distributor is different somehow and requires different slot sizes to achieve the correct total advance.
