I'm looking for help thinking my way through a problem. Mitsubishi grey market tractor from the '70s. It has a 2 cylinder diesel, KE95, makes about 22 hp (supposedly). It's all mechanical. The only wire on the engine is on the glow plugs. I haven't checked compression yet, but it fires up quickly and idles nice. Injectors both crack at around 1700 psi, which is spec, and give nice chatter, and mist, and don't leak. Cylinder head just got a new valve job, and decked. New head gasket (of course) and just re-torqued today. It runs great up to about 1500 - 1600 rpm, when it starts to bog and spit white smoke. If I push it, rpm doesn't go beyond about 1800 (redline is around 2500), and it's missing and spitting until I throttle it back to about 1500, where it likes to be. Both cylinders doing the spitting and missing. I ran it with the exhaust manifold off, and watched it. No leaks. No coolant loss. No blowby (I was watching that too). Also ran it with an aux tank, no change. I'm open to suggestion.
