I recently rebuilt the walbro crab on my brison 2.4 . I replaced: pump diaphram, pump check valves, fuel screen and gasket. Also diaphram, lever and float needle. The old float needle I noticed had a soft rubber type tip, new one is all metal.

Reason for rebuild was engine would go lean and die after a while of nose up running at WOT. After rebuild, I noticed much better fuel draw and no more running lean at WOT. However I did notice, that no matter how I set the low needle, it would still load up on me. It was fine in the air, never had a lag. but on the ground, during starting I noticed fuel dripping out of the carb. It would get severly flooded to the point all I could do was pinch off the fuel line and flip till she started. Then I would unclip the line and she would stay running fine.

After reading the article and noting my 2 symptoms after the rebuild I took apart the diaphram area and bent the arm down a hair. Hopefully next weekend I will notice the change!
