'''Did the mechanic do this when the engine was cold? Sometimes adjusting the overhead when the engine is cold....if the mechanic sets the valve lash too tight as the engine heats up and the metal expands the valve setting will tighten up. I always run the over head on my N14 after coming off the road or run it till it's hot then set the valves so that when it reaches operating temperature it's where the adjustment is suppose to be.'''''italic text''
