Mag Checks - A cure for rough running.
During my PPL training I recall a time when during the power checks in a PA28 the engine began to run roughly on one mag. The instructor took over and did some high revving and messing with the mixture for a minute or so and then the rough running went away. It was at that time during my training that I already had too much to remember so I forgot the details of what happened.
I recalled this yesterday when doing power checks on a PA28, there wasn't any rough running but I wanted to recall what was done to cure any rough running if it did appear during the power checks. I'm no longer in touch with the instructor so can't ask what it was that he did.
Thoughts?
