Been working on this project fourtrax that i bought, and finished cleaning carb and motor. Then went to test compression which was zero, and try to jump it off but nothing happened... no light turned on, nothing switched the starter solenoid out and all those wires and went to jump it off and it started sparking like crazy, tried it both ways with the solenoid so it couldn’t have been backwards. I don’t know what it was. Any ideas?
