I have a D4 that has been sitting for many years. I worked on the fuel system and installed new spark plugs in preparation to start the pony engine and then eventually the main engine. The main engine does not have a starter. They pony engine requires a hand crank (pulley on the back of the pony engine). Does anyone know where to obtain whatever is used to rap around the pulley so it can be cranked? Also, is there an easy way to check the operation of the magneto? Thank you in advance for your response.
