Hi all, hoping someone can direct me to a source for this carburetor. I've spent several hours searching and can find every number except mine. The saw is a Yard Machines model MS40 and of course any search into MS40 brings up Stihl. Shame on them for using this model number! It seems that yard machines is really MTD but again that's no help. The carburetor is a "Walbro WT750". I can find similar Carbs on ebay and rebuild parts on the Walbro site but cannot find the actual carb? Anyone know where this rascal is hiding?
