I would talk to the boss and OK getting it adjusted. Lots of good little mom and pops outs there. Just put a shout off to stay away from the interstate bandits. Other wise you way not get home.
Boss has a mechanic. They told me can't do much adjsting. Maybe they know something i dont about the transmission.
Clutch adjustment is a breeze. A solo clutch is self adjusting and I've been told that the adjuster tends to seize up if the driver only ever floats because it takes so long for the clutch to wear down enough to auto adjust.
Some clutches are a problem. Hope it works out for you to get home. I thank Solo is one of the worst.
