Okay so i just got this thing and here's what happened. Took it out and drove it for a good 30 minutes and everything was PERFECT. Parked it for 2 seconds and tried to crank it back up, would not start. Turned over but would start up. I put jumper cables on it for about 5 minutes and finally got it to start. Rode it about 5 minutes and this awful tapping/knocking sound started from the top of the motor and it shut off on me. Tried to start it, dead again. Got jumper cables on it and started it. As I pulled it into the yard it started to get hot. Next day, I put a brand new battery in it. Still did not want to start. Finally Held start button down for 2 minutes and it started (got lucky) but got hot while just sitting there idling. HELP ME, Idk if it's 2 different Problems with the electrical starting issue and the knocking sound or if their working together.
