bigger is not allways better when it comes to venturi size, the larger venturis only assist in top end performance not good down low, also the butterfly type is much more responsive than the slide type. the 10mm walbro is a much better improvement than the stock limited carb.

RD, i've got a 16.5mm race ported walbro with the lot, i'd say that'd beat your 10mm, and my stock piston port carb also had the adjustment screws. but anyway, enough of screwing up your 4 sale page.

everyone with a stock cag carb, it's worth buying RD's carb you'll definately notice a difference

r1 guess what? my 10 mm carb only costs $20. how much did your 16.5mm walbro cost? would you like a 17.5mm walbro?

remember if you attach a larger than stock carb more of that petrol and air will need some where to go, therefore your motor be running to rich. You can tune your stock carb to perform just aswell.

yes, lets not go to big on the venturi size.

do people realise that they have a 49cc engine? they dont need a really big venturi. my 11.7mm walbro performs just as well as the walbro 603 on a cag.
