My rig always seemed like it started hard even with 200k on it but now with a fresh 10:1 motor it just BARELY moves it most of the time not even enough to start... I could probably spin it faster by hand(well maybe not). I have a brand new battery that I just charged and I even hooked up a jumpstarter to it and it didn't turn it fast enough to start... sounds like grinding. Sometimes when it does get it movin it's will have plenty of power then it will almost slow to a crawl. Anybody else have this problem?
