Put another cam and rocker assembly in it and it should be fine. Be sure and change the oil. Use a good oil filter such as a WIX (NAPA OR CARQUEST), or Polaris and good oil(MOBIL 1 Synthetic 0w-40 or Polaris oil). The camshaft wears out due to improper oil change intervals or carb flooding putting gas in the oil. It also might not be a bad idea to clean carb and inspect needles for wear. Thanks
