DM,
You can postulate all you like. Everything in post# 11 is true & correct.
Page 9 of the Edel tuning guide states a fuel starvation issue could be caused by low fuel pressure & 4-5 psi is reqd, MINIMUM. NOT MAXIMUM.
Further, Edel carbs come with the small 0.093" n/seats. The comp series Carter AFBs came with larger 0.1015" n/seats, with sizes as large as 0.120" available. Larger n/seats changes fuel level & makes fuel level harder to control, but up to 10 psi was controllable.
The metal in Edel carbs might be cheaper, but it does not cause flooding unless it is porous or seals fail to seal.
The OPs problem may well be a float issue, either leaking or binding.
You must be working on different Edel/AFB carbs than the rest of us. As long as the pressure is kept under 10 psi, the float tangs do not bend & claiming that 'high rpms' bends the tangs shows a lack of understanding how carburetion works. A LOT of fuel is being used at higher rpms, fuel level drops, & the float tang is less likely to be in contact with the needle. One of the causes of lean mixture at high rpms is insufficient fuel supply through the n/seat, float is lower not higher.
