thank you, petec for your help. i HAVEchecked out that website and have actually followed the instructions to the letter. i have also found other articles on geistware. the steps listed on the site have not solve the problem. i think there is a leak somewhere but cannot find where. i have sent the engine to YSservice twice. the first time the piston ring was replaced along with bearings, pushrods, diaphragm and gaskets. did not solve the problem. the 2nd service was to "adjust loose backplate disc valve". still no correction to the problem. i wonder if i should replace the valves and springs. i am at a loss to figure this out.i am thinking there is an "internal" leak somewhere. i believe that would certainly cause idle problems. the fuel system does not leak. ihave not noticed any leaking fuel from the engine.i am using the proper fuel and also a new YSglowplug. soitremains a mystery.
