Edelbrock acts like it is flooding? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Asahi123 · 07-19-2012, 02:55 PM

I have a 71 chevy 350 auto with a 6 month old edelbrock 1406 carb. I am having a issue with idling when hot. I have to keep my foot on the accelatrator just to keep it running. It has ran fine up until this point. I noticed fuel dripping from the secondary shaft on the passengers side. I replaced my fuel pump. Cleaned my lines and cleaned my fuel filter it kind with the brass looking type filter. The carb acts like it is flooding. Once it dies you have to wait and let it cool off maybe 5 minutes and then keep the accelerator to the floor. Once your above 30mph it runs fine but below that it acts like it is flooding. So any advice would be appricated.

Pick up a fuel pressure regulator. The 1406 carb does not like anything above about 4.5psi. Anything more than that will actually cause the carb to leak fuel down into the intake at idle, and cause stumbling / flooding / hard starts. As I understand it the extra fuel pressure pushes the needles up off the seats (no carb mechanic..) But it makes sense to me.

I have the same carb. Adjust able fuel pressure regulator did the trick for me. I run mine at 4 psi.

i'd first replace your fuel filter as cleaning is not a surefire way to service them as with time they get petrified crap in them and restrict flow
