My Edelbrock starting pouring fuel out of the vent tubes even while the bike was running. I assumed it was a defective needle and seat or possibly spoke with Edelbrock tech support and they suggested the needle and seat. I was sent a replacement needle and seat but when I took the float bowl off it didn't appear to be the same piece. I spoke with the tech support and requested them to take a look at the carb. Turns out my needle and seat WAS defective and they also completely rebuilt the carb. I was very satisfied with the customer service Chris Silva provided. My carb was waiting for me on my front porch when I got home from work yesterday. I have had my carb over 1 year so I wasn't expecting everything to be done at no cost to me. Edelbrock customer service.
