• 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.

The fuel shutoff valve on the S2A I fly is very stiff. I was going to suggest they replace it but it's no longer made and the replacement is a different valve and kit from Aviat that is no doubt expensive and time consuming to install.

Anyone have experience disassembling and repairing the original valve? It's an Imperial 104HD. I thought maybe it could be disassembled and lubed.
