I bought a Honda Master Series lawnmower last spring. Since last summer, once I start the engine and mow grass for about 20 minutes, the engine begins to miss and sputter. I must disengage the blade for several minutes and allow the engine to idle before the engine will run normally again. I have changed the spark plug, installed a new air filter, and tried fresh gasoline; but none of these actions have solved the problem. I even took the mower back to the dealer, but they claimed there was nothing wrong.
Have you heard of similar complaints from other Honda owners? What else can I do to solve the problem?
