Hi Everyone,
I have an old Heron 1cc diesel which I am trying to get back from the dead. The last time I ran a diesel was when I was about 13 (many, many years ago. Here's a hint, Ian Smith had not declared UDI in Rhodesia)
The engine has been cleaned and I have managed to get it to fire, but only after priming a little fuel in the port. I do not know what the correct setting for the needle valve or the compression should be. I have initially set the needle valve to 3 turns open and the compression at a point where the engine fires. Can anyone give me some pointers?
