Hi and welcome to mightyram. Sorry to hear of your dads' passing. We actually have a thread dedicated to noobs and what to do when you get your hands on your first truck -

IMO the G63B engine is a good starting point if you aren't super handy with a wrench. They are easy to work on, are pretty forgiving and in most situations cheaper to fix than the 4G54 or the injected 4G64 from later model trucks. The factory carbs on Mitsubishi engines take some skill and knowledge to overhaul - it isn't a gadget for the inexperienced to tackle straight up. Hopefully you won't run into any major problems with your dad's old truck but that is what the forum is for, so ask questions if you aren't having much luck with the sites' search engine and post up progress and pics as you go along the way.
