Can someone tell me what the cfm is on my carb? It has two different primary rods in it and I am trying to do a basic setup using Edelbrock's site. It's either a 600 or a 750. Looking at my jet sizes (the primary's are bigger than the secondary's) makes me think that it is a 750 because that is the way the marine edelbrock's marine 750 is set up, but the engine is a 1995 Merc 350 mag (250 h.p.) which leads me to believe that it is most likely a 600 and that the jets were put in backwards by the last owner's mech (remember two different rods). It is a Weber 9770SA. Thanks.
