To Prime Or Not To Prime? That is the question!
I was recently party to a discussion on whether or not to prime. In particular the standard plants found in Piper 28 series etc.
I have always been told that you should prime when the engine is cold, 5 squirts and if not sure give it 2 for a good measure.
I have now heard the view that you should not as it may cause an engine fire!
I know that pumping the throtel when cranking the engine on start as this may cause a carb blow back and subsequent fire. That is why you should prime.
Can any one cast light experience or anecdote on this?
