[QUOTE="Phil Davies, post: 115094, member: 2541"] The reason the fuel is metered is specifically so high downdraft angles can be used, unlike with air metering. What I can tell you is that there is a known 'low air flow' fuel pick up problem on GP's - precisely because of the fuel delivery method and route (and there is a fix!). What I can also tell you is that 100% you will see a performance increase from Gardners over GPs, precisely because of better fuel metering and delivery and its consequent atomisation into the choke. One important item that lots of peeps with Gardners forget is that they do not automatically enthalpy compensate like GP's (because of the fuel delivery method), that is one reason why they are so easily adjustable - because they have to be each time! What I also also know is that Ron's float chambers do not froth, unlike the amal's (despite what amal used to say to the contrary). [/QUOTE]
