Welcome to the Zone.
Kanter sells two overhaul kits for the 230 tornado. No experience with their parts sets, but they found me a NOS camshaft to exchange for my old one.
Took good care of me.

I bought my parts "piece meal" from ebay, and various vendors. Took forever.
All of the manuals are at the top of the page. I simply printed off sections as I needed them, and took that to the garage for reference.
You will get opinions both ways on whether to repower it, or to keep it original.
I completely restored my truck (engine and all), so I have enough experience to give further advice if you decide to keep it original.
