Following up on post number 1 of this string.
I went back to the airfield today and got another five gallons of Av Gas (after watching that youtube video maybe I shouldn't had):eek2: Anyway, the car ran great as you all have reported with your cars. The idle was so consistent and smooth as well as the low rpm pull starts from stop. Car runs great. I think my previous problem was a fluke.
As for the video, I had no idea of the history of lead and it's toxicity. Provided the video is correct?

How much a gallon was it?

$7.14 per gallon
