• 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 have an Ellison on my 0-320. I had it rebuilt last year (45 hours ago). The cost was $650. Everything worked great up until a few months ago when it started dripping fuel after shutdown. The engine runs just fine including doing acro, but who wants a drip? If I don't shut off the tank shutoff, it will drip at a rate of 1 drip per 10 seconds. If I turn on the aux pump (like I had to do to check a fitting) it really starts to pour out. There seems to be no info on this that I can find. The Troubleshooting Guide only says that more than a tablespoon sometimes occurs on a new TBI but will disappear after the fuel inlet control valves have seated within the first 10 hours. Any ideas?
