I know the discussion about fuel evaporation has been around the block a few times. I have a Edelbrock 1450 on my 454 and I was wondering if anyone has had experience with that carb leaking into the manifold after the engine is turned off. After sitting 24 hours my carb is dry. Besides evaporation can it be leaking or maybe syphoning back. I also run the 6 psi Edelbrock mechanical fuel pump which should have a check valve. Any input appreciated.
