Hi Bert you miss a big factor that spray bar mouth( jet) is under the barrel.Not over the butterfly.I am repetaedly mentioning this.So fuel jet(spray bar) cant match any bernoulli law.It is directly under changing vacuum but unfortunately just reverse of Butterfly/venturi type carb.(Walbro).Make an analogy please ,how it can be if main jet was under the butterfly instead over it in a Walbro carb?Just same here because of barrel/Glow type carb.So regulator needle gets crazy to supply.
