It does look like there was some form of leak of oil from the Dec gear box
Forget about that. It has nothing whatsoever to do with the clutches. The oil in the gearbox is simply the light lithium grease we used back then which is now separating. Open the gearbox cover, wipe away any residue and apply some heavier grease to the spur gears and to the spindles. You mount will run like new.

Thanks! It does look like there was some form of leak of oil from the Dec gear box. I will do that when I am out the next time. It is good to know that this will work under power.
