Hey,
I need a new carby for my 4AC, and one of my mates said some stuff about getting an oversized carby so it will suck more fuel down and increase performance.
Is he talking shit, or are these things available(if so where from),and do they work as he has told me?
I realise if they are around that it wont make a big difference in performance, but some is better than none!
Thanks to anyone that can help me out with this.

to be blunt he's talking shit
if the carb is already supplying enough air, with the correct amount of fuel... it will make no difference except possibly worse everywhere except WOT..
if the carby is undersized, then a carby with larger throats can help allow the engine to suck in more air IF, and only IF, the engine needs more air..
if the carb is not the restriction......
what you might want to do is look to some of the early euro cars with downdraft Webers... early 70's FIAT's come to mind..
aiui, webers have better atomisation than Aisan's, so it may help a bit... don't go overboard on size tho...
another option might be the falcon 32/36.....
but as always, if you don't know why you need it, you probably don't.

ps, whatever carb you get will have to be re-jetted. this can be an expensive exercise if you don't know what you are doing... at $5-10 each, the cost of jest quickly adds up..
