Thanks for a great demonstration on 2 methods to find TDC .I am the one who did not know how . I am working on an engine that has been rebuilt recently , and has developed a bad miss . After checking all other possibility’s . The engine builder told me to do a leak down test.which I have never done in my 82 years ,but I know to do this you need to find TDC . Of each cyl. You are testing. Thank S MORT BOB
