Assuming it has the origianl motor, it wil be an integral head with a 2-bbl carb. Take the toop of the air cleaner, if you see one round hole it's the Monojet, if you see 2 slightly squarish holes it's the 2 bbl. A little bick finicky to work on but decent carbs.
You will find NO chrome parts unless you have them chromed. You wil find NO hop up parts (other than cam stuff) unless you replace the head with an earlier version, in which case none of your brackets will work and your carb won't fit.
Spark plugs, any auto parts store, do not run Champion. Bosch and NGK are good but pricey.
