Chainsaw Repair

I am still having lean issues. A guy on another site was having the same problem. Runs fine at first then leans out after long cuts. (Still waiting on carb kit, fuel line,and filter from dealer BTW.) So he tore the carb down and the inlet screen was semi plugged with what it looks like that foam they put inside aftermarket fuel filters. So i tore my carb apart again and found my screen semi plugged also. and i also have a after market filter with the foam inside. I started the saw earlier today and couldn't blip it because it was so lean. after i cleaned the carb and put an OEM filter back in it and started it tonight, it seems to have plenty of fuel.
