• 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.

Hey guys,
I have removed the engine from my Pitts and have it on a maintenance stand. The prop is removed. I removed the upper spark plugs just to relieve the compression in order to turn it over by hand.
When I turn the crankshaft about every half turn there is a very audible click. Just a single click every half revolution or so.
Is this normal, and if so, or not so, what is it?
Thanks.

Dan
