[Fot] Zenith-Stromberg needle specs

[Stutzmans]

Strombergs operate with a deeper jet level than we're used to with SUs. 
Early TR6 carbs have a jet level of .080 below the bridge.  Late TR6 carbs 
use a jet level of .125 below the bridge.  You should first drop the jets to 
.125 for increased richness.  Then try the XKE B1E needle.
