• 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.

I know this is not really a Pitts question but many of the older ones have the pressure carbs so I will ask anyway. I have a 160 Lyc with a Bendix Pressure Carb. When I amat cruse power (2300RPM)and lean it, it starts to lose rpm very slightly as soon as come of off full rich. It will probably loose 100 rpm before it starts running rough. Is this normal?
I have had Ellisons and float carbs on aircraft and they would not really lose rpm before running rough. How do you lean these pressure carbs?
