• 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 bought into a Pitts that sat in a barn for 18 years untouched. In addition to the sitting in Eastern Virginia unused, it has an old-style crankshaft with the light-duty flange, so we decided a teardown was in order. It also has a superior cam that has timing that is slightly off.

Superior's SB that covers the cam basically states that "we tested it, works fine and essentially meets spec despite the angles being slightly different than lycomings and should make rated HP". (attached)

Does anyone have any pre-internet knowledge on anything further with this camshaft?
