Incomplete combustion
because the engine is cold and you need to keep the engine warm.
Yes the reason for that is because the engine is over heated and when its cold the engine is nice and cold perfect for starting conditions.
Most diesel engines are hard to start when it is cold. Plugging the diesel engine block heater in will help the engine start.
Hesitation. Stumble. Backfire. Flooding. Hard cold start. Hard warm start. Poor idle. Poor mpg. Smell of fuel.
Means to start the engine while it is cold (And has not been running for a few hours so the engine has gone cold)
Check the timing on it along with your plugs and wires.The backfire is from gas not burning completely and ignites in the exhaust.Most likely its the timing which can be set by turning the distrib very very little at a time till prob is solved.
it should start at cold
Bad thermostat? Doesn't close enough to allow engine to warm up properly
It is not so much hard for a car to start when the engine is cold as it is easier for a car to start when the engine is warm.Cars that are hard to start in the cold are usually not new cars any more and because of wear and tear there is more likely to be something that doesnt work as well. when fuel is warm it ignites more easily.

It's when you start the engine when it is either really cold out, or the car has been sitting in a temperature region for a while where it has not been run and exposed to cold conditions. This is where more than 50% of engine wear comes from, the cold start because the oil has thickened and therefore does not pump through to the most crucial parts of the engine as fast. best advice is to use the manufacturer recommend oil viscosity (ex: 5w30 or 5w20) thicker oil does not help. And the use of synthetic and synthetic blend oils does help to reduce engine wear at a cold start.
