a thought I just had (it happens) for consideration of the group ....
What would happen if under those conditions, one were to spray the fuel lines,
possibly the float bowls, with a product like Dust Off? It's basically
compressed air, but?gets very cold when used.? I'm guessing it's a bad idea
because of the temperature differentials and?what it might do to the metal
parts subjected to such extremes, but I'm just guessing.?

Subject: [TR] Fuel percolation
I've seen percolation on several cars over the last year. ?I agree with
Randall, I think it is a result of the fuel they are selling now; the
addition of the ethanol lowers the boiling point of the fuel. ?I've seen
fuel literally boiling in the jets of an SU H6 equipped TR4 recently. ?This
tends to happen after the car sits for about 15 to 20 minutes after shutdown
and the heat has enough time to "soak" the carb bowls and jets. ?The TR4 in
question did have a heat shield and we had rerouted the fuel line away from
heat sources. ?We were also running a low pressure electric fuel pump in
