Welcome on the board! I remember seeing this car for sale a few times and thinking it was a sharp one. Tune-up parts and technique suggestions in this thread. The engine is probably about due for its first valve adjustment. Carburetor operation and repair manuals and links to training movies and carb repair/modification threads are posted here for free download. Hope the previous owner kept the original carb rather than turning it in as a core when he installed that rebuilt carburetor. You'll want to replace any hoses and belts not already replaced, including the fuel line hoses (don't forget the piece that connects the fuel tank to the hardline, back at the back of the car); you may at the same time wish to do the Fuel line mod. Cost and difficulty of a disc brake swap depends on which disc brake swap you do; there are many ways of doing this.
