I'm still new to this site... I'm still new to the LUV in general so PLEASE EXCUSE MY IGNORANCE as I am not a seasoned mechanic by any means.
Ok... with that in mind, I have recently acquired a 79 LUV 4x4. The previous owner bought it in 94 with the intention of fixing it. However he either didn't know what he was doing, or he didn't have the time to. The truck sat parked since the date he bought it. When I finally got the truck, the head and the valve cover and everything else above it (air filter, carb, etc...) was all removed and sitting either in the bed or in the cab. The stuff in the bed was all rusted and seized to hell (including the head and valves and all that crap

) I know basic to moderate things about how the engine works and all that stuff. (At least I think) But I recently just found out what an AIR PUMP and AIR INJECTOR look like and they are rusted solid.
Now here's my question: Do I need that stuff or am I better off without it? This truck will eventually travel with me to California in a few years when I move there so I don't want to remove too many emissions crap... or is that the way to go? I don't know, that's why I'm posting this ridiculously long question.
Thanks! Any help would be appreciated.
