After putting some fresh gas in the tank, I hit the key and it fired up after some cranking. It ran great:
…for about 15 seconds, and then it started running rough. On restart it was running even worse. I took a quick look at the engine and noticed that fuel was running out of the sides of the carb. The fuel bowls were overflowing.
My first thought was that the needle valves connected to the bowl floats were leaking. After a little more investigation I figured out that they were being overwhelmed by the fuel pump.
I took a closer look at the fuel pump setup, and discovered that there was no regulator. The Edelbrock carb is expecting something around 6psi coming in, and this pump was putting out 15+ psi.
I ordered a regulator and some other parts from Summit, but based on the UPS tracking, the package disappeared after it arrived at one of the UPS hub sites. After a few days of no updates, I contacted Summit. They offered to refund or re-order the missing parts. I asked for a re-order, which they did immediately, and shipped it out via FedEx expedited shipping.
