Having a little hesitation at mid throttle when i punch it. Removed fuel bowl from my cart which is a carb i bought new from buggiesunlimited. Only thing i can think of is that it prevents sediment from going into tiny pin hole leading to drain valve on fuel bowl. Even so, i wouldnt think it would do crap for that hahah. Anyone seen this or know exactly what it is for or did it fall out of carb somewhere more important
