Regardless of whether inline fuel filters are used on gassers or not, there is just no logical reason I can make to myself why one would want to nor need to remove the internal screen. It is the absolute last defense the carb has against fuel contamination that could still happen with an inline filter. When the tiny drilled passages of a Walbro carb get crud in them it can be almost impossible to remove the crud without complete disassembly of the carb. A task that most users are not capable of so the carb becomes a throw away item.

I repeat, Mr Lee usually recommends removing the screen when it gets plugged with crud. Why on earth would you want to remove this valuable item even if you add back an inline filter. If anything happens to the filter, you're right back where you started only this time, your carb is plugged where the screen could have protected it. Most lawn equipment / chainsaws that use Walbro carb have inline filters yet they still retain that valuable screen. And ..... that's all I want to say about that and frankly, I'm sorry I ever brought up the subject.
