I have a 1987 Yamaha warrior 350. I got it from a friend, he blew it up. I dropped a new bottom and and top and into it. It seems as though it is stuck in reverse. The reverse selector shaft does not turn enough to go into drive. The reverse light is not on and I have no spark. Wether or not the clutch is pulled the tires are difficult to turn and when cranking the motor the tires spin backwards. Any help is appreciated. Thanks!
