Spark Knock or "preignition" or if you can if you can remember the early 80's the term "labor knock" was also thrown about. those conditions all all from timing that is to high, retard the timing a little bit and it should all clear right up. Do you have the timing set with a light, or did you just set it by ear? Or static time when building [or working on] the motor just to get it going and then it was so close you wanted to try it. If you put a light on it did you set it at an idle or an all in type thing at a certain rpm? Jim
