You guys, this sounds JUST like my bad starter problem I had with (2) of my big reds. Can you guys record what a typical cranking sounds like and post it here, or on youtube, or just email me a clip. I can tell you if it sounds like mine did before I replaced my starters.
Both my big reds ALWAYS sounded like they could just barely turn the engine over, like the battery was almost dead. And the problem persisted even with a NEW, fresh, fully charged battery AND being jumped off also.
After the starter replacement... not even like the same machine. I would say roughly that cranking RPM increased about 300%.
