Has anyone had an issue with the pump lid sealing back on top of the pump? I haven't attempted this mod, I was just curious if it was a concern.
it shouldn't be a problem the top has a square section 'o' ring fitted and if you are careful should go back together ok. the seal is very cheep to buy if you wanted to replace it.
So let me get this strait.....
You want to shim up the MAIN spring ONLY? (or is there others to shim?)
What would shimming it up do such that it only has half the compression travel it used to have do for drivability??? (ie - spring can compress 1" (2.54cm) and you shim it so that its precompressed down to a 1/2" (1.27cm) already) <--would that be adequate?
Also, does anyone thats done this mod have any idea of its side effects like fuel milage, drivability, long term effects, etc...??
ejust, the governor mod raises the rpm at which the governor begins to cut off fuel, so will not by itself affect low rpm performance at all.

I would be concerned about disturbing and then relying on a 20+ year old seal. That's why I would recommend buying a bosch pump rebuild kit, which contains all the seals, gaskets, and o-rings, and are available cheap (like around $20). Then whatever seal you touch when working inside the pump, replace. All the rubber parts, including those governor lid seals and also any o-rings (like the throttle input shaft o-ring, and the full load adjust screw o-ring) can get quite flattened and loose their resilience over 20+ years.

Nobody here(Winnipeg) will sell a kit like that: you have any leads in your neck of the woods?
