T24 Carb problem

[John Mason]

David. I am no specialist on carbs but if it run reasonably well when the choke is out. That leads me to think that the closed choke is correcting the air to petrol ratio and it runs reasonably well. Opening the choke upsets this and the engine stops (to much air). The level of petrol in the float chamber is critical to get the correct air/petrol ratio. As air is drawn down the Ventura this alters the air pressure making it lower than normal air pressure thus more petrol to more air keeping the balance of petrol/air the same whatever the throttle setting.
So your thinking of float level could be the answer. Is it to low.
