    if it was completely gone it wouldnt run, there wouldnt be any compression.
    Borrow a compretion tester if you know anyone who has one or take it to a garage to get the compretion tested. If its low then the rings might want changing

    Running rough, bogging and loss of power are indications if you don't have a compression tester. I should know, I wore a single ring though the chrome in 600mi!
