gas lost

[Keith Tedford]

I have had the same problem with our L78. Let the car sit for a day or two after a long run and the carb is basically empty. Fill the float bowls through the vent and the car starts right up. Start it and shut if off cold. A week later the car starts like it had been running five minutes ago. I added the GM oil baffle that snaps in between the heads. It keeps most of the hot oil off the intake. I also blocked the heat cross over, and double gasketed the carb to intake to slow down heat transfer. That helped quite a bit. I'm getting an aluminum heat shield that goes in between the carb and intake to keep more heat away from the carb. I believe that the carb and intake don't need that much extra heat for summer running. I never had this problem with the Q'jet on our 455 Lemans, even with the cross over open.
