Hey Bob.
Thank you very much for the info.
Yesterday I took the filter cover and tried to prime but no gas came from the little tube. I think i over tighted the filter assembly and all I did is loosened those screw a little. Now I see fuel coming in when I prime. Guess what, It started in the first pull. Thanks a bunch.
But still my engine surges after a through carb cleaning. Wondering if I need to remove it again or go with what I have. Actually I spend more than 15hrs with this issue (reading online + removing and cleaning + put it back)
