D6 9U Clutch Question

I am not visualizing this very well, so a shot in the dark here. So I better go out back and look a 9u over. The clutch lever has to run the clutch brake and the transmission interlock. Are these hocked up? Is the clutch lever on the peg backwards?

Could be clutch out of adjustment and not snapping over centre when engaged. Is there any resistance on the lever? Is engine running or stopped? There is something wrong deeper down. Linkage to interlock is bent won't be helpful. All part of the fun!

Thank you both for checking in.
The transmission interlock linkage is straight and in line - not angled, twisted, bent, or binding. Same for the clutch brake linkage. If I were to shorten the adjustment between the lever and clutch arm enough to move the arm up a couple inches with each pull, the lever would be out over the hood, nearly out of reach to the operator. I would have to shorten the interlock rod too, since it pushes the interlock to it's internal stop - that limits the present lever travel at the handle to a total of about 4 inches. Forward, the interlock bottoms, rearward, the arm impacts the crossmember.
The parts book diagram of the clutch control linkage plainly shows the lever in relation to the crossmember. Something is out of whack here. I am staring directly at, but cannot see it.
Any other ideas and/or suggestions? Thanks, Jeff

Look deeper....The clutch yoke lever arm is keyed and clamped to the yoke shaft which usually makes a good trouble free connection but the yoke itself relies on a key between yoke and shaft. Not uncommon to have the key and keyway get hogged out to where you lose indexing of the linkage.

Thank You, Mr. Old Magnet:
I will certainly check the cross shaft, arm, and keyway condition. Don't know if it would do me any good, though. The total upward travel of the clutch arm, with only about 4 inches of total travel on the control stick - is about 3/4 inches, up and down. I will disconnect the rod to the transmission interlock to see if it might be one of he culprits. The clutch brake and clutch cross shaft and internal mechanism seem to work fine when disconnected and isolated from the lever. Jeff
