Has anyone seen these? They have no jets and instead use a ‘fuel metering rod’ and claim to have better atomisation than fuel injection.
Because the fuel supply is controlled by the volume of air flowing past the fuel metering rod and the floatbowl is also kept at the same pressure as air flowing through the carb they also automatically compensate for changes in altitude, air density or clogged filters.
