Pics and advice would greatly be appreciated to open things up under the hood. I want to get rid of anything and everything I can from the evap canister to emissions off the carb, this is for a 87 by the way.

Purple arrow = charcoal canister. keep this to keep the gas fumes from stinking up the cab.
yellow question mark = relay for the ptc heater. keep this intact if you wish to use the ptc heater to prevent icing over the carb. also requires that little sensor in the radiator to be intact as well.
blue arrow = horn relay. keep this for the obvious
top green x = these are vacuum switches. These can be scrapped for just the weber. However these can be incorporated into the power steering setup and the ac setup to help bump the idle. A diaphragm will also need to be added so it can pull the linkage on the carb.
lower right green x = excess vacuum lines. can you say SCRAP?????
lower left green x = some sort of check valve. The valve may serve a purpose for the evap canister, but not too certain here.
The light blue x is the vacuum sensor. This won't be necessary anymore.
Red x = altitude compensator. I have no earthly idea how the heck that this works. my guess is that it senses a difference in atmospheric pressure with something mechanical inside, and allows for a slight vacuum that then goes to a switch or a check valve and upps the idle or fuel somehow. With a weber it's complete garbage and can go.
upper left light green x = I have no idea what this is, other than the fact that it can grow legs and disappear with a weber.
Black x = no clue here either. it can be trashed.

hmmm. be careful ditching the emissions stuff. i know its shit and annoying but i would be checking with the epa regarding what the consequences of removing it are. i know in australia individuals can face fines of up to $10,000 depending on the vehicle and what has been removed.
