You'll find tune-up parts and technique suggestions in this thread. Cap and rotor information (long thread, worth reading the whole thing) here. You're probably due or overdue for a valve adjustment, and carburetor operation and repair manuals and links to training movies and carb repair/modification threads are posted here for free download. Once you've got the basics taken care of, you'll want to look into the Fuel line mod and the HEI upgrade .
