I have recently installed a new Skytech lightweight starter in my 1974 112A, N3389T. It does not seem to turn the engine over much faster than the old starter. I installed one of these in an earlier commander of mine and what a difference it made, whipped it right around. I am told its something to do with the guage of the battery cable. Can one of you smart guys shed some light on this and how to fix it.. Thanks,,vince
