C-172 C Engine Management Questions

Thanks Tom! :yes:

The starter motor, if it is still running, is completely inaudible, so I'm not sure if this is really our problem, but it certainly warrants a look.

I was also surprised at how few engines require the additive:



So, with our only Lyc carbureted engine being the O-360-A4M in the Archer, it would appear that we don't need the additive in any of the planes. But, at least it doesn't appear harmful to the A4M... Or is it?

If your A4M doesn't need the snake oil you will be better off running 20W50 and Cam Guard in all your engines.
