750 Edelbrock issue

I had an Eddy 750 on my 340 (modified to about 375 HP) and it ran great. It did smell very gassy when I drove it. I downsized the front (primary) jets 2 sizes and that made a big difference. It was still GREAT when I put my foot in it, but driving in town and in traffic was way better. After 10 years with the 750, I switched to the Eddy 650 Thunder. It is a great carb.
