Update: The diesel Metro runs pretty well right now. As I thought, the injection timing was too retarded and one injector had a bad spray pattern. It takes 2 springs inside the governor to get 3900 rpm from the Kubota. Shifts will be at 3600 or so. I moved the top governed speed out of the way because it is so annoying to hit the governor like a rev limiter on a gas engine just as you are shifting.
Smoke is almost non existant now. But the fuse block melted down yesterday when I turned on the blinkers. I don't want to push my luck until the fuse block is changed out. The headlights also don't work.
A bit of advice for anyone wanting to put something like this together....forget using the generator Kubota engine with 1800rpm decal on the valve cover....like mine. This governor is completely different than the ones rated 3000 or 3600rpm. It is a "2 fork" type, with very few adjustments. You need the 3 arm governor to make it drivable. This has a speed variable injection pump timing and a torque limiter to cut excess exhaust smoke. I wish I had known this sooner. My injection timing is by shims. It is now set to run well at 3000 but rattles and knocks pretty good at idle. It costs over $1000 to buy the parts I really need for the centrifugal advancer. I'll keep looking for used pieces. It is a little peppier with the re shimmed injection pump now. Keep you posted.....
