Thanks for the replies. I double checked, and it definitely is a choke to shut down. There is a fitting with a butterfly where the air cleaner pipe connects to the intake manifold. I always idle way back before shut down, and it stops immediately. This appears to be the "factory" setup, and I don't see anything obvious on the injection pump where a shutdown cable should be connected. I'm pretty sure my friends JD 1070 with a Yanmar 3 cyl has the same setup. I am sure that machine is factory original. Should I add a fuel solenoid? What happens if I am forgetfull and try to start against a closed fuel solenoid? I guess I would need to put in a regular keyed ignition switch, or a relay to not allow glowplug/starter unless fuel is on.
