    I fly an old 182 on occasion. I have no problems with it except for one question. Upon climbing through about 9,500 the engine will surge on occasion. It's not a constant thing, just every now and then. It hasn't gotten any worse and there are no others symptoms that I've noticed. I thought maybe I wasn't leaning enough but I don't think thats it. Anyone have any ideas?

    What does the oil pressure needle do on these occasions? Is it a surge up or down from the governed setting?

    Hard to diagnose a problem with no data to reference.

    Is it running MoGas or 100LL? Is it one surge or a sustained series?

    It sounds like I pulled power back momentarily.

    When it happens again, note what the MP and oil pressure do. Why do you think your initial thought of not being lean enough is incorrect?
