Fuel Starvation?

Need more info. Going from cruising to WOT & engine dies?
- what rpm does the engine reach before it dies?
- same rpm in each gear?
- how long does the engine take to come back to life?

For reasons known only to Edel, they used pidling little 0.093" n/seats in their carbs. These will be too small for a large cu in engine that gets up to 6000 rpm.
