eric that was an issue in thought for me it was kinda planted by the info post i made above ...all i can say there is with the 32-34 carb i have on my bike the argument of not having high rpm punch is just slaugtered .....im way pass there about car carb not delivering ...sheesh the problem with the weber 2 stage carbs is taming to much delivery in my results and once you get that match up you couldnt have a better system for oldwing motors in my opinon ...simple and absolutly no power loss ..in fact a huge boost if dialed in right ... :builder: :thanks:
