If you start the pony motor, let it run until it warms up, then engage the main engine WITHOUT fuel and let the pony turn over the diesel for about 10-15 minutes. The Pony shares its coolant with the diesel and also pre heats the oil for proper lubrication. So now, 20+ minutes later, your diesel's oil and coolant are warmed up, and the pony exhauset runs through the diesel intake manifold preheating the intake air. Now, the diesel will fire right up with full lubrication and oil pressure and won't take long to reach running temperature. This was how pony motors were supposed to be used clear down to subzero temperatures.
