The compression was checked and determined to be approximately 65 pounds per square inch. Some engines have been observed to have less than 50 pounds per square inch and will still crank and run. This author is not aware of any recommended specification on compression.

Start and run the engine when it is cold and also when it is still hot from previous running. This will help determine where the air adjustment cap needs to be set when starting up the engine. Most twin cylinder engines need to be fully choked when starting up cold. Close the air cap completely and give the kick a smooth firm push. Then open up the air cap about 1/4 turn and press the kick again a couple of times to start the engine. Don’t jump on the kick assembly and put excessive pressure on the kick assembly parts. An engine that is still hot from a previous run can likely be restarted without completely closing the air cap.

This set of nice original Maytag script plugs were installed in the engine after it had been test run and all necessary adjustments were completed. They have a small letter "B" beside the name Champion. A set of original Eisemann rubber boots were installed to cover the connection of the plug wire terminal and spark plug.
