I'm having an issue shifting into 1st gear from neutral. No problem shifting into any other gear including reverse. When I depress the foot pedal it doesn't go into 1st gear. After repeatedly pressing it sometimes it will go into 1st gear, other times I have to rock the machine slightly and then it will go into 1st gear. I took the right side cover off and removed the clutches to get a better look. I've taken all the parts of the shifting mechanism off thinking I would find a worn part but everything looks fine. When I watch the shifting action from neutral to 1st gear, the part that engages the shift star (drum) is pushing on the peg that is connected to the shift star but it can't push it far enough down to get it out of neutral before it bottoms out. What am I missing? Is the issue actually inside the transmission?
Thanks for any and all help.
