Variator needs to be greased..see inverse zirk on left hand side of engine...in the center of the spinnig part. You will have to make a fitting..I used a needle fitting with the needle removed. -3 pumps every 2,000 to 3,000 miles. Carb probly needs to be cleaned. Check petcock for free flow. Clean exhaust. Good luck! If you have not done so dump old gas and check tank for rust!
