Everyone on this list should have a good Thanksgiving, because all the bad luck seems to be with me. My '69 Spit ran great for about 1k miles, then developed a very loud knocking sound and complete lack of power. Fortunately, I had a '74 engine lying around, so I put that in. Lo and behold, after about 1k miles, it started having the same problem. With the first engine, I didn't open the engine up to find out what was wrong (I was saving that pleasure for the winter), but I've done a little investigation on the '74 engine. It idles fine, but when it gets up to about 1500 rpm it starts knocking, very loud knocking. There is visible smoke coming out of the push-rod journals for 1 cylinder (#4) when it is knocking. Here's the real question. I rebuilt the '74 engine myself, but had the head worked on by a local machine shop. They were supposed to convert it to a no-lead-head so I've been using unleaded gas. Looking at my bills from them, they didn't charge me for the conversion (no new valves/seats), just the machine work, so I'm not too confident that I was using the right gas. What are the symptoms of using unleaded in a leaded engine?
