Fuel leak question

[cobrakiwi]

if you run an electric fuel pump only turn pump off before you turn your car off, hit the gas pedal a few times to empty some of the fuel out of the webbers.
This used to work for me on a 289 with IDA's I had a few years back.

The problem is the fuel trapped inside the pump conducts in the carb body. The carb heats up and the fuel inside the pump conduct has probably some air trapped along the way, which expands with the heat and pushes the gasoline out the pump jet. The pump draws the gasoline from the bottom of the bowl, so a lower bowl level should not be of much help.
I think only shielding or some type of evacuation of the hot air should help.
I am going to try a pair of Muffin type fans mounted behind each side vent and improve the heat-shields I have already made.

Starting instructions after hot shutdown of webers. Push gas pedal half way to the floor and hold that position , then turn the ignition key and she will start right up.

May sound to easy a fix but works every time.

The extra fuel that has dribbled and perculated out of your carbs and down the manifold is not enough to hurt your engine or rings if you give the engine more air during these start up conditions.

Buy holding the pedal half way to the floor the throttle plate is half way open allowing the engine to suck in the nesessary amount of air to lean out the hot, rich and vapourised condition found in intake manifold, carbs and heads.

These conditions mainly found after first hour of engine shut-down.

Getting into this habit of start up can be used in all conditions.
