Engine Starting Techniques – what works for you?

Recently, some club pilots have had difficulty starting the engines in the club planes with GMA being particularly tough at times.

If you’ve been successful starting the club aircraft engines recently in the colder weather, we would like to hear about the technique you used.  Sharing knowledge will help fellow pilots who may benefit from your technique and have better success.

Please use the comments below to describe the steps you use successfully to start the engines including the following details:

  • Aircraft ident.
  • Primer (setting & use)
  • Mixture (setting & use)
  • Throttle (setting & use)
  • Starter key (setting & use)
  • Sequence of actions.
  • How successful it works (i.e. works every time, works some of the time, etc.)

Hopefully this will identify what techniques are most successful.

Standard Procedures, Primers, Flight Safety.

There has been some discussion in the club about primers lately and I would like to share a few facts for those interested.

As you may or may not know, the primer pumps fuel directly into the manifold upstream of the intake valve and does not go through the carburetor. If you leave the primer unlocked, fuel can get sucked through the primer in addition to the fuel going through the carburetor. That creates an extremely rich mixture. To the point where the engine may run rough or in extreme cases, not at all. Bottom line is that with an unlocked primer, you will run extremely rich to the point of running very rough.

Hope this clarifies the questions people have been asking.
