Thinking the cleaning process must've removed the lubricants on the linkages, I lubricated them again. After removing, greasing, and re-installing them WITHOUT making any adjustment whatsooever, the same problem subsists! The idle speed is still very high (at least 1,500rpm, I reckon).

So I thought the next logical step would have been to adjust the idle speed by adjusting the screw at the air-intake/throttle manifold. Well guess what... the darn idle speed wont go down! This after making sure that the throttle itself is almost close! The screw is almost removed... all to no avail. This car doesn't have any vacuum assisted/power whatever... in fact, it has the old 'pull to start' switch.

Okidoki.... so maybe this problem just coincided with the degreasing. I did experiment with the Injection Pump and I found out that when you pull up the linkage at its side/rear (if you disconnect it from the other linkages), the idle would drop sufficiently, almost to the point of cutting out. Why is that? Could that be it? Rats! My injection pump seems to have a problem! Could this be because I also popped a quart of 2T Oil on a tankful of diesel (read somewhere here that 2T Oil [for motorcycles, I think] is better than any other oil for fuel because it is meant to burn)?

Lost again...
