- the mixture will become leaner as the size of the bleed is increased'
- Carter Carbs, Dave Emanuel: 'As bleed size is enlarged, the vacuum reqd to initiate fuel flow is INCREASED. Conversely, a reduction in bleed size reduces vacuum signal requirements & the fuel flow is more easily initiated.'
- Graham Bell, 4 stroke Performance Tuning: 'a large MAB leans the mixture, especially at higher rpm'
- Graham Bell, Modern Engine Tuning: ' The AB reduces the signal from the discharge nozzle....a larger AB leans the mixture.'
Here are a couple of hints to help you understand how an AB works:
- high school physics. The real physics, not your version when it suits you.
- what happens if you block the fuel bowl vent.
