So I am working on my Father’s quad and hoping to get some help. It’s a 95 425 Magnum 4×4 and it acts like the clutch is engaged all the time? I start it in neutral and it runs / idles good however as soon as I put it in gear it starts moving and will stall if I stop it once in gear. I changed the belt but that had no effect on the symptoms and it happens in both 2WD & AWD. Not sure what to do from here. I looked through a manual I downloaded but couldn’t find anything about clutch adjustment. Has anyone done this before?
Any advice is appreciated!

Thanks,
Chris
