BIngo,,,,,,, a very slow and hard starter drag !!! Only hot.????????Wont start or starter wont turn it over?
It's been my experience that hot dragging only was alway's starter itself .Just happened a few years ago on my 66 Chevy pickup. Installed new starter took care of hot slow crank.Start's hot just like it was cold.Ground on batt has bad connection at batt or to frame. Run two grounds of thick guage wire. One to block and one to frame.
Old guy told me thats difference between hot dragging and cold draging. Smart sum bitch!!
Hot dragging is ground issue.
