Finally got my old 4x4 quad (honcho) running but it wont move when i first got the motor running it moved for about 5 min both forward and reverse now it is stuck in nuetral unless I pull up on it really hard then it will go into reverse but as soon as I let go right back into nuetral it wont even go into forward any advice also anyone know where I can get a diagram of the inside of my tranny I belive the brand is comet??
