hi, i am having a problem with starters. It is a 168 tooth flywheel so i have the staggard mount starter. The engine is 11.5:1 I was using a stock starter on the motor and it worked fine for about 3 weeks. Then when i would turn the key the starter would turn the motor over but the starter would make a loud "crack" noise. I figured that it was because of the high compression so i got a high torque starter today and put it in. It is doing the same thing. And the stock starter had an S and an R terminal and the high torque starter only has 1 smaller terminal. Does the S wire go to this terminal because thats how i wired it? Does anyone have any ideas of what the problem could be? The flywheel is a little rough on the edges but it doesnt look like a major problem.
