I have a troy bilt string trimmer, The carb has a metal plate covering the diaphram. The plate has a vent hole in it. I just replaced the primer bulb on this trimmer. When I pump the primer bulb it fills with gas and gas pours out of the vent hole on the plate. I'm thinking this is not right. The trimmer did start. Ran about 4 seconds and stalled. I noticed that the primer bulb was mostly empty. I put the trimmer back in the garage where it proceeded to leak all over the floor. What kind of defect is occurring here?
