• 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.

Guys,

I'm down to very few remaining parts to go thru on my Waco Rebuild. It has a (not-original) D-3 fuel valve that has been installed since 1968. I finally got around to opening it up today and wasn't too excited about what I found.

The shaft that runs thru the center is surrounded by a tapered piece of cork. The cork was in awful shape. The assembly that my fuel valve mounts to is fairly complex and I wouldn't enjoy replacing it. I"ll have to rebuild this or mount a similar valve in the same position.

I assume some warbird guys, Howard DGA guys, etc have been there and done that before me. I have a couple of questions for those that have.

Does this valve normally weep? Will the valve work without the cork installed (It seems stable, but maybe it would leak?) ?

Is there a common way these valves have been rebuilt? or are they normally Sh!!canned and a modern valve put in place?

I'll post some pictures in a few minutes from another device.

Regards
Dan
