Oh, I need to add something to that last post. No way could I have rebuilt that OD without the constant help of those on this Forum. I could probably assemble at least 150 posts and responses, including from a number of you who clearly are the world's data bank for these cars. So I wanted that clear.
Forty-five years ago, over a mere $50, I passed on a cute little MGB and drove 60 miles north of Town to buy a strange car called a TR4. That was surely a major turning point, a fork in the road. I have so many stories, and have learned so much. Like who Kettering was. I also remember two bits of good advice from a guy in a garage. Ninety-nice percent of your troubles are spark or fuel, and no matter how small it is, don't get under it without jack stands.
