Basic Tuning: HELP!

You need to get a timing light. If you don't want to spring for an adjustable one you can get a damper timing tape to tell how many degrees advanced your timing is at different rpms. Try unplugging your vacuum advance and checking what your timing is at 4k rpm. For a ballpark number it should be around 34-36 degrees. Then hook your vacuum line to the full vacuum port on your carb and take it for a drive. If it pings you might need to retard it a bit. That is probably all you need to be messing with at this point.
