     * The first ones were called Andrews Flowmasters. \\ They used a rubber adapter flange and a hose clamp to hold the carb on to the manifold and a K&N air cleaner held on by a hose clamp.
     * Later issues of this carb (called Screaming Eagle) were cast with a flange to allow the carb to bolt to the manifold.

+===== Starting =====
+**Choke**: \\
+The carburetor choke knob (enrichenor) should be pulled up for initial or cold starting. \\
+Push the knob down as soon as the engine is warm enough to run without stumbling. \\
+You can ride with the knob up for the first few blocks.
+===== Tuning =====
+**Air / fuel mixture**: \\
+The air/fuel mixture screw is set initially at one full turn outward from the full in position. \\
+Do not set idle speed or smoothness with this screw. The screw must be set within 1/8 turn of the one full turn position for optimum performance.\\
+**Engine Idle Speed**: \\
+Idle speed is set with the throttle stop screw. Set engine idle speed at 1000 - 1150 RPM with engine at normal operating temperature. \\
+**Accelerator pump**: \\
+If your engine has an off-idle hesitation, you may have to adjust the accelerator pump stroke. \\
+Do this by adjusting the accelerator pump screw after all other adjustments have been made. \\
+Off-idle hesitation can be caused by either a too lean or too rich pump stroke. So you will have to determine which way to turn the screw by experimenting. \\
+Turn the screw 1/4 turn at a time. \\
+**Jetting**: \\
+If your engine is relatively unmodified, it will run well with the jets that come in the carburetor. \\
+Depending on the level of performance modifications, it may run better with different size jets. \\
+See the jet chart above. \\
+NOTE: \\
+All the carburetor jets are slightly rich. If the engine runs too rich just off idle, use a #65 slow speed. \\
+If the engine is rough or jerky at 55-65 mph, remove the blank intermediate speed jet and install a
+#80. \\
+**Flanged model** \\
