Walbro is a massive company, so dont worry about it. They know whats up with fuel delivery.
I bet every small engine you will come across will have a walbro carb on it. When I see a non walbro carb I look at it like its retarded (not related but still a good example). Theres a reason for that though, and its because they are on thier game and are a reliable company with reliable products.
But like everything else mass produced, occasionally one will go bad or die prematurely. If that happens to you dont bash walbro as it happens with every product all the time. Just send it back for a new one
I wish computer parts were as reliable.
