The weber has no provision for increasing throttle opening for when the AC clutch is engaged. I just increase the idle ever so slightly in warm/hot weather to compensate for the AC compressor drag. You just have to find the point the engine idles smooth with AC on and will not diesel on shutdown.

Mine has the electric choke option. Manual choke kit can be added to replace the electric choke if you change your mind later. The Weber conversion needs only one vac. line. That is to supply vac. advance to the distributor.

If your state has emission testing for your vehicle the weber conversion may NOT be for you.

Also consider using a fuel pressure regulator between the fuel pump and the weber.

There is probably the answer to every possible question to the weber conversion somewhere on this forum.The search button is your friend. The amount of knowledge on this forum for Montero/Raider community is truly amazing.
