    I had a checkflight for round about 2 hrs with 3 starts/landings.
    It's possibe to watch a small part of these flights at my latest video.

    The result till now , everything works, dry airfilter....no leaks recognizable.

    I will open the old oilump and will check what happens, perhaps I upload a Video.

    Thanks!

    Hi!

    it‘s leaking again, I think the oilpump won‘t be the reason 🤷*♂️.

    Hopefully it's not the seal on the rotary valve shaft. I believe that can leak oil back into the carb. Is the level in the small bottle going down? JImChuk

    Try cleaning the check valve. Look for cracks in the tube that goes from the check valve to the carb.

    I have the same issue as everyone stated. Does anyone know the hose size for the oil pump ? ID and OD. I put a set of calipers on it and it showed slightly more than 4mm. What is being used ? I cannot seem to get the specs from the IPC. Seems suppliers are back ordered against their assigned mfg pn. Avmech
