There's not much to most centrifugal clutches. I believe it's pretty straightforward. Of course I've only seen the little ones, so yours could be more involved. But usually on something like this, the real difficulty is in fighting the new springs back on. Since they're new, and stiff, it can be a real problem. Sometimes there's special tools, and/or techniques that'll help. But it sounds like the kit is the way to go. Might end up being easy.
