Thanks! I didn't really do it myself. I had a mechanic friend come over and I 'assisted'. He let me do a lot of it though. I really don't know how long it's been like that and it's been sitting for the past 6 years. I've been working on restoring it for about the past year. Here's a link to the first test drive last week, just before I discovered the problem. I only discovered it because the valve cover gasket was torn and leaking a bit, so I noticed it when I replaced the gasket. I thought it sounded OK.
