The Biplane Forum is a large global active community of biplane builders, owners and pilots. From Pitts to Skybolts, to older barnstormers, all types are welcome. In addition to our active community, our content boasts exhaustive technical information which is often sought after for projects and maintenance. This information has accumulated over the 12+ years the forum has been in existence.

The Biplane Forum is a private community. Subscriptions are only $49.99/year or $6.99/month to gain access to this great community and unmatched source of information not found anywhere else on the web. We are also a great resource for non biplane users, since many GA aircraft are built the same way (fabric and tube construction). Annual membership also comes with two BiplaneForum.com decals.

Considering that the RSA fuel injection setup specifies an idle mixture such that an rpm rise at idle of 25-50 is achieved when bringing the mixture control to idle cut off, and further considering that many engine gurus advocate agressive leaning on the ground to prevent lead fouling. Why does RSA make thier reccomendation? Would not it be better combining the 2 schools of thought by simply leaning the idle mixture as lean as possible while maintaining satisfactory throttle response from idle (600) to 1200 ish where the idle circut is no longer in play?

Thanks
