Re: Engine Stall
First check the hose to the power breaks and make sure it is not leaking, or that the diaphram in the break booster is not bleading off vacuum - I doubt this is the problem but worth a quick look.
Probably the idle tubes are cloggin in the Carb , easy fix -Remove air cleaner, remove air cleaner bracket on top of carb. Remove butterfly (choke plate) and butterfly rod, remove two 'screws'just inside the ventura and lift out the idle tubes, they hang below the part that you just unscrewed. Clean out the tubes with a piece of wire and reassemble. I have done this once, and once one of my idle tubes had fallen out and I had to press it back in place.
IMHO - you will not be happy with this setup until you upgrade the ignition. I did the GM-HEI, and love it. Dollars well spent. The TR upgrade is supposed to be even better and cheaper. My '89 Laredo idles perfectly now, and it used to have similar symptoms to what you are describing with your ride. Hope this helps - there is a technical page on the web that spells out what I just described above plus a lot of other cool tricks.
