I've got a Yard-Man Chipper/Shredder Vac 5.5HP, M#24A-060F402 (247.770380) I've tried looking this up online for hours and can't find a replacement carburetor. When gas is poured into the tank it leaks all out of the carburetor. I took it off and now I can't find a replacement. This model seems hard to find. Does anyone have any suggestions?
