650 Thunder AVS

I recently installed an Eddy 650 Thunder AVS on my 68 340 and find I'm running rich all the time. The guy at Summit where I bought it says I should install fuel pressure regulator to limit fuel to 6psi or install an eddy fuel pump. I do smell fuel once in a while.

Has anyone installed this carb or had the problem?


I have one on my 340. Had to jet it down as it was too rich from the factory. Runs great now. Make sure there is not more than 5.5psi Fuel press.
