mikeh Posted January 27, 2016 Report Share Posted January 27, 2016 Hi The Kinner Motors 'Instructions for Operation and Maintenance of R-55 Aircraft Engines' states for shut down: 'The recommended practice is to shut off the fuel supply and let the engine run until the fuel in the carburetor has been been consumed. If this is done regularly the time between overhauls will be greatly increased. The 'Pilot's Flight Operating Instructions for Army model PT-22 Airplanes' states 'cut switch' (turn the mags off). What do you guys do? Thanks Link to comment Share on other sites More sharing options...
cnehus Posted February 3, 2016 Report Share Posted February 3, 2016 Always check mag switch prior to shut down ( this could save you injury next time your pulling the prop thru with mags in off position only to have the engine kick or start with out warning due to an ignition system fault), engine around idle, both mags off briefly to check operation of switch and "P" leads. than idle cut off with mixture as any other engine. I would NOT drain the fuel from the carb at shut down as this will only dry our seals and gaskets giving you additional issues. Link to comment Share on other sites More sharing options...
kennethchapman Posted February 3, 2016 Report Share Posted February 3, 2016 I shut it off with the mags per the flight manual. Additionally, I always check the brakes and make sure the mags will ground on initial taxi. Link to comment Share on other sites More sharing options...
