• 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.

Lycoming aeio-360-a1a for pitts s2a

Got shave in oil so the engine was in to maintenance shop changing cam and lifters, oil pump and bearings.... Anyway, rest is all back on and ready. Engine was going smooth when delivered, but now it is rough as hell... Either way i adjust the mixture screw on the rs5a injector it is either very rich or too lean. It starts to fire at about 1900-2200 range rpm. Timing is checked, fuel divider looked clean inside. Why does it not go smooth when thing has just been bolted back on? Any ideas?
