    Compression Test What pressure ?

    Hi All My 80 is now approaching 100,000 miles. I have replaced the BEB 15,000 miles ago. I still have a little trouble with smoke when the engine is under load, it also uses a little oil. What compression should I have on a test. ? If it is low then would a ring change be in order. ? Mal
