Hi everyone. I am hoping to find a service manual or exploded view diagram for a Lincoln 110cc Automatic Mini quad. Or any advice ect. Something seems to be locking up inside. However the quad has sat for a while. I have lubed EVERYTHING and think the piston does go up and down when I move the flywheel clockwise, but it locks going forward. Thanks and if photo,s or any more info is needed please let me know.
