Office of Steam Forum for Model & Toy Steam Gas & Hot Air Engines

As part of my "Peanut - Rider" routine maintenance, I remove the plug and insert a pipe cleaner soaked
in meths to clean the passage out. Oil from the displacer piston bushing can accumulate in the passageway and reach the piston and cause problems. I normally clean and lubricate my engine before
each run especially after it has been sitting awhile.
