After reading a bunch of posts on run-away diesels, it seem many of the causes are related to having the throttle lever / governor shaft spline misaligned, after having the pump cover re and re.
I'm inclined to start looking here, rather than making adjustments to screws that I understand very little about.........plus, it's more variables to consider if I start making compounding adjustments.
Getting back to throttle lever / governor shaft spline alignment........is it really so, that having the lever off by just 1 tiny spline, that the engine can redline upon starting, as was the case with mine?
When I was about to put the lever onto the governor shaft [ the governor shaft has a slot in the top, like a screwdriver blade would fit into ] I first turned the shaft all of the way counter clock wise, as in full throttle position. Then, I lined up the mark [ that I had scratched into the lever with an awl ] on the lever with said gov shaft slot, and seated the lever. I checked the rotation of the throttle, and it had a full range of movement and *seemed* to operate like it did before I ever got into the pump.
Did I do this right? Now, I'm thinking, I could have rotated the gov shaft fully clockwise [ throttle off ] before aligning my lever mark and seating the lever onto the spline.........as in 180 deg off from the 1st way. Can this be done? I'm trying to remember from memory if the gov shaft HAS a full 180 deg rotation or not.
Getting back to moving the throttle lever only 1 spline.............if my engine is running away at start up, which way do I need to realign the throttle lever, clockwise [ throttle on ] or counter clockwise [ throttle off ]?
I can see this may take some experimenting [ multiple attempts ] to get the alignment correct............... and that last laver spring is a real bugger to get back on.
Can I just have that last spring in place on the gov shaft, but have it relaxed and not wound up for these tests?
