Thanks Renze for your guidance, so far have replaced head gasket, cleaned out clogged radiator, replaced rev cable, oil change and cleaned the worst dirt I have ever found in an oil filter I was suprised it was still rotating. Still have to seal power steer ram and add a coolant bottle to the radiator so I don't waste it on the ground. I am adding a 63mm s/s pipe for the exhuast and dreaming of a turbo. What I would like to know is how you adjust diesel pump on my 5945? I read other posts and still are not clear on where to adjust this pump, the cold start nut just rotates and does not seem to affect it. So I am wanting comfirmation on where to adjust, as I want to see a little black smoke. CHEERS all
