Question and Answers


craftsman model 917.272751 valve adjustment


Thank you for your question. I usually set both of the valves at .005� and never had a problem. I have looked up your model and it is a 310000 series engine. The image below has all of the specifications for your engine. The intake is .003� to .005� and the exhaust is .005� to .007�. Make sure to adjust the valves when the engine is cold. A warm engine will throw the settings off. If you have any other questions, please feel free to reply below.

Thank you for using Manage my life. Mark T.
