Crap in your fuel line is another reason not to use the "T" fitting in a 2 line system. Any crap that comes from the can, ends up on the carburetor side of the fuel system. So it is almost meaningless to have a filtered clunk. Now if the fuel is filtered very well, before your fuel tank, then I suppose it would not matter.
So whether you have a screen in your carb or not, it really comes down to how well you filter your fuel.
I have always respected Mr. Lees articles, and I grew up reading them in RCM. His info was very valuable to me as a beginning R/Cer, and helped solve a lot of issues I had back then.
