i have always contended that down to 0f or even lower you do not need
the flame heater. i just went out and started mine and at 10f it started
in less than 10 seconds. granted you could certainly tell it was cold by
the way not all cylinders fired evenly, but it started right up as it
always does. on warmer days it starts almost instantly. by the way
correct timing is very important to this happening in a diesel. but back
to cold starting. a diesel MUST crank fast. 300 rpm is ideal, even when
very cold. this takes very good batteries and very clean connections and
the right weight oil for the temp. also when cranking, hold in the
clutch, even if in neutral to remove the load of the cold gear oil. the
next trick is to flood the engine, (you cannot really flood a diesel)
hold the throttle on the floor until it starts and slowly let it up as
it starts running to maintain say 1000 - 1200 rpm. the excess injected
fuel acts to seal the piston rings and makes compression better.
