Hey guy i picked up a Yerf Doc Spiderbox 150cc a few weeks ago that needs some work, I plan to fix it ride it for a while then sell it for mini parts lol. Well we started to work on it yesterday and wanted to see if it would turn over, Put fresh gas in hooked a battery up and when we hit the fire switch it made a mean noise like a whining, The engine didnt turn over at all it was just a loud whine. Any suggestions?
