750 sf3 air fuel ratio

Curiosity John,
Do you have a balance pipe between the carbs?
I ask because I have seen engines have funny areas in the fueling and a lot of "standoff" in that area, this has been cured with a large balance pipe between the manifolds.
Quite a strange fuel curve though!

Ring playing comes naturally to the boys from the "other side" so I hear

I'm totally confused! ???
All this banter about oxygen levels and revs but I would just like to say that despite all the technical big words and mumbo jumbo I haven't seen anywhere enough information or intellegent input, beside's Cosis reference to rings, to even hazard a guess.
Aren't we talking an SF3? If so then what were the throttle opening ratios. This is the information needed to try and sort out if the carbs/jetting is the issue.
What is the jetting information, at what stage of the throttle travel did this occur?
Really guys? :
If you can't sort the basics, stick to the bling.
Rod, need to have beer with Cosi.

Fitting exhaust temperature gauge to each header should tell if you are in danger of melting a piston? I ran this my first season of racing.
From following this discussion it does seem to hint at exhaust problem. I had similar problem (flat spot, but I didn?t have O2 meters) once from a cracked dislodged straight through "baffle" in an SFC 2/1.
