Hi KillerMiller, hows it going with your restoration... Looking good. I started a similar project with a 1988 Terrano 1, 2.4 Z24 petrol (identical in many aspects to the Pathy from the same era). If I can offer my tuppence worth of knowledge (Haha), if you can see your engine cooling system has had water instead of antifreeze in it, then take a close look at your core plugs before it all goes back in (is it already too late !!!) I saw markings on mine and popped them out in situ (tough to get access on some) and found they were corroded and ready to leak, but also, a huge build up of sludge, rust and muck in the block just behind the plug, which was greatly reducing the coolant circulation and causing overheating. The other thing you might want to check, is the coolant thermo choke (on the right hand side of your carb photo). If there has been a lot of muck and sludge in the cooling system, it almost definitely has accumulated in that housing rendering the auto choke inoperative, provoking higher revs at start up but not dropping off. If its completely clean inside, it should work, but if not, its really hard to find a replacement and in my case, I just had to block mine off. Good luck...
