I have a gas 284. It's an orphan. The only thing International is the name plate. Japanese hybrid. I price a gas tank and fenders @ the dealer. Tank $800, fenders $2000 each. They tell me they used this engine in '71-'72 Ford Couriers (try and find one of those). Carb is easy. Check and see if leak is on plunger. I was able to get that at the dealer. It is leather. Soak it in something to swell it up if it is dry. Couldn't find a fuel pump, so I put an electric fuel pump on (low pressure) that worked good. I also install a Pertronix electronic module replacing the points. Probably a good little tractor when new. My tractor has a loader. My 284 is stuck right now. When I get it running I'm selling it ASAP.
