Hi Bruce. I guess we keep going until the problem arrives - normally half way up a hill where you can't stop! I have made a "bonnet prop" which I can install within minutes once stopped.
My temperature measurements indicate that the carb temp is within a degree or two of the fuel tank temp. However when the tank is "super hot", a stop of 10 mins or so and then bonnet off is sufficient to drop the carb temp by a couple of degrees and away we go again.
What I would like to find out is what did Austin do when they sold to India etc. Are todays problems down to fuel or equipment?
Our latest "attack" was on a hot day and long run with some good hill climbing in 2nd. Difficult to replicate after implementing some changes. I have an idea of "Teeing" off a bottle of fuel mix - 10% heating fuel and when the "attack" comes, switch over. We will see!
