• 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.

So, I am hooking up the throttle cable to the throttle linkage on the carb. With throttle disconnected the first half of throttle arm movement there is no friction force at all, the butterfly moves just fine, no resistance whatsoever. Movement past the halfway to full open results in a feeling like its working against spring pressure. If I release the throttle arm it springs back to mid-position.

When the throttle cable is connected, no resistance to halfway, then a forcefull resistance to full open, if I release throttle it springs back to half position...

What the heck is going on here? I have no experience with a PS-5C. it can't be normal. I'm about ready to unload my .45 on it!
