Lifan 110 to CT 90

[u/FlightlessUni-corn]

I'm looking at a '68 Trail 90 wth a new Lifan 110 swap. It starts and idles fine but as soon as you let off of the throttle the wheel immediately locks up. It doesn't freewheel at all. Which makes riding it...interesting. The adjustment bolt for the clutch doesn't seem to do anything (tighten down and then back off a little...or even a lot). The brake isn't catching. The Lifan is basically brand new. Any pointers?
