After getting the seats back in the car, it was time for the next larger concentric circle according to my restoration theory. This one was a journey of about 50 miles circling the house. It included some twisty roads, some uphill climbs, and about 15 miles of interstate. Overall, the car ran very well. There was a little pinging under load, which might have been the gas, but I will recheck the timing to be sure. It is stable at 80+ MPH, and returns to a perfect idle every time. We are getting close….
