New member here with a question. Yesterday I pulled the plugs to clean and regap them, changed my fuel filters, and just general maintenance getting ready to go fishing Monday. When I finished, I pumped the bulb to crank it up to check my work and saw gas running down the motor on the port side. There's a small brass tube at the top left of each carb. The top carb on the port side has gas pouring out of this tube when you pump the bulb. I feel like something is stuck inside the carb causing this. All six carbs were rebuilt last fall. What would be my problem and what's the fix? Thanks in advance for any help.
