Well, I worked on my injectors today. Perhaps my methods are unorthodox, but
they seem to work. I swapped the nozzles for new ones. I then gauged the
breaking pressures with the new nozzles. I replaced shims to get close to the
breaking pressures I wanted. I then found that I could hand lap (fine
sandpaper on flat) the injector mating surface of top half of injector to increase
breaking pressure, or the ends of the spring to lower it. I was able to balance
them to within a few psi of each other. Impressive the fast stoccatto when
they were done, along with the choking mist of trucker cologne. Van seems to
have quit its smoking altogether, despite the fact that I increased the fueling
a bit. On WOT up Big Hill I managed hit 1170°F on pyrometer. I think I'll
leave it alone now. On to rerouting crankcase venting.
