Installing a mini-starter on a friends 383 and when I try to put the starter on the lower stud it will stop short about A 1/4" from sitting flush, if I remove the lower stud I can get the starter to sit flush but then I cannot get the stud to start. Any Ideas, I have installed mini-starters before without any issues, never seen this scenario. The starter is a new Denso unit bought from Mancini a few years ago that he is just getting around to using.
