Idle-Eze
The Idle-
Eze™ feature allows you to set your idle speed while maintaining the correct orientation of
the butterflies with the transfer slots. This provides better control of the idle mixture screws, and
results in a cleaner idle, crisper throttle response, and quicker tuning. The Idle-
Eze™ also helps in
overcoming idling difficulties in engines with larger camshafts.

Setup & Tuning instructions:
Adjust the butterflies before installing the carburetor on the engine. On engines that idle at 1000 RPM
or higher, set both the primary and secondary butterflies open by the same amount. As a starting
point (with the carburetor upside down), set the butterflies such that they ex
pose approximately .020”
of the transfer slots. The transfer slots are the thin slots milled in the baseplates and are
approximately 5/16” in length (Fig. 19).
Figure 19
With .020” showing, the transfer slot will give the appearance of a little square situated below the
butterflies (Fig. 20).
