After some help from members of this forum, I was able to diagnose a couple of problems with the fuel system on my '87 Trooper. I rebuilt the carburetor and replaced the fuel pump** and was able to get it running after increasing the idle speed (only to ~1000rpm).

A previous owner or mechanic drilled out the plug on the idle mixture adjustment screw. Can anyone advise me of a way to adjust the idle mixture without taking it to a shop?

Thanks for your help.

** The mechanical fuel pump was a pain to replace, but by removing the EGR valve (?) it was at least possible.
