The internally tapered spray nozzle is the more responsive to the perpendicular airstream across it. I attribute this to a greater volume of air flow passing across the wider cross-section at any given air speed. At a constant air speed at the same slide opening, the generated low pressure at...

Hi All. So far, LG2 for consideration? Any alternatives to...? Any reasons why not...? Ta. Owen.

Thank you for replying. By asking, I hoped to find that a technical assessment of nozzle exit tapers had already been done by researchers. In the last 40+ years there has been almost no development by the manufacturer of british motorcycle carburettors except for: 1. a hard coating to the zinc...

Thank you for replying. My thoughts are that the fuel will leave the sharp edge better (smaller).

Hi. I am re-engineering a 40+ year old carburettor design. The current throttle slide has stress raiser flaws and is the same material as the mixing chamber that it slide interfaces with. The prototype slides were printed in ABS for fitment trials. The functional trials used Acetal allowing for...

Hi. First post so I hope I have the correct thread location. I am reverse engineering a 40+ year old vertical slide carburettor design i.e. the venturi is horizontal. The current spray nozzle protudes vertically into the airflow but is straight sided and flat across the exit. Option 1...
