Freak 0 #1 Posted May 14, 2017 I have been trying to fix an old string weedeater (Homelite ST155) It has a Walbro WT-220 carb on it. The gasket kit I got has the wrong diaphragm and I can't find the right one no matter how many variations of the 220 carb I look at. I was thinking of just buying another carb. How can I best find a 13mm carb with the bolt holes the right distance apart? 32mm. Share this post Link to post Share on other sites
