    Engine Exhausting

    Well , this is for the engine knowledgeable. I've been tooling around with a flat 4 ( well known brand) engine for education reasons ; replaced exhaust valves ( hand lapped) into recut seats. Compression "seems" much improved , on pull thru ( not leak down tested ,at this stage). Here's the query, pulling through on the exhaust stroke the exhaust is sucking in prior to the actual exhaust ........as if the exhaust valve opens maybe 10 -15 degrees before the piston hits BDC. Is this typical or "normal" or is the timing of the cam misaligned?? The case has not been split as only the top end has been worked on.

  14. Hi...you kindly responded to my call for aircraft purchase suggestions and recommended the Jabiru 230. I see you have one, and also a Zenith 601...the Zenith was suggested to me and I am aware of one for sale...can I get your comments comparing the two aircraft? Adam
