Question
need to know the valve settings for this engine,it has a noise and a knock when decelerating down a hill,or on high rev.,this engine is on a Rokon,thanks for the help.....TOM

Answer
Hello Tom:

Send me the Model Numbers Off the Engine, Please. With these I can Locate the Proper Manual and Better Assist you. However, you can Set the Valves on this Engine at .004in - .006in Intake and .008in - .010in Exhaust and the Engine Should Run Just Fine, Provided this is the Easy Start Engine (OHV). Hope this Helps. I am Here if You Require More Assistance. Let Me Know What Happens, Please. Thanks.

Good Luck
