I’m still fairly new to the game and when I first started making sausage I opted for a off brand 7lb vertical stuff that has given me nothing but headaches. Even when using the largest tube (not summer sausage size) I still get gasket blowout and skipping gears. Almost impossible to turn. I chill the meat and stuffer in the freezer. Do you think it’s used error or should I up my game to a better stuffer? Any help would be appreciated.
