94's use vacuum secondary's which look for low vacuum to indicate you are doing 30 and want to be doing 70 which is where the problem lies. Model A's are a low vacuum motor. Have people run 94's on them absolutely some block the secondary completely and choke down jets so she runs right but then no secondaries when you do need it. Whats a fellow to do? Stromberg 97, buy set .44 jets and the secondaries are mechanical (Yeah problem solved) I pretty much have same engine as you I just bought the BIG97 stock jets are .45 which another friend of mine runs and he ended with the .44's. I bought a pair when I got mine, my friend bought from .33 up to .45 and tried them all. Now I don't have to, and neither do you. 94 and 97 use same manifold bonus!
