• 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).

I am not much of a tech head when it comes to engines, but I would like some opinions on what maybe causing the IO-360A1A? (carby)in the S1-S that I fly, to surge briefly while flying aerobatics? It has only started doing this and only on some flights.
The cowls are off and itsgetting looked at now.


It first happened when I was on the 45deg upline doing multiple rolls, and today it happenon 45degdown line after a 1/2 neg snap.


Anyonegot any ideas?Edited by: aeroz_z
