An engine question....
I know this is not a Private Flying topic per say but it has been in the Engineering forum for a few days with no response at all.
Can someone give me some advice?
I have a Continental A65 in my a/c. It runs smoothly and is cleared for mogas. I use avgas and mogas depending on what is easier to get hold of.
As I open the throttle on take off or after a descent, the power increases but not as evenly as I think it should.
As I apply full power with a steady and progressive opening of the throttle to the stop, the power increases smoothly to 2000 rpm and then stops increasing. It will then jump to 2200 rpm and then continue to rise smoothly.
What is the reason for this "flat spot" and is it something I should be concerned about?
