I don't know if his 324's will work or not, they may. I had a WT-324-1 with an 11.1 mm venturi that I tried to get to work on mine. It was new, but I never could get it to idle well. I ended up buying the G26 carb from my LHS and had no further problems. It was plug and play. If you want my 324, I'll send it to you for postage.
