Fuel pump seems to work...BUT...

Problem: Fuel isn't getting to carb.
Steps I've taken:

- Gas tank was professionally cleaned and several gallons of clean gas placed into tank. The bottom of the gas tank sits 1 ft above and 3 ft behind the Atomic 4. (C&C 30 MKI).

- New 1/4" marine grade fuel line installed from the tank to the engine and double clamped at both ends. Suction was applied to engine side of gas line (before attaching the line to the engine) and gas was freely pulled from tank.

- Sediment bowl was removed, cleaned and filled with gas as much as possible when securely reinstalled.

- Fuel pump was checked by working the baler up and down while the 1/4" copper tubing from pump to carb was removed. The pump outlet was covered with a very small piece of thin plastic (from a grocery bag). When baler was lifted there was suction at the fuel pump outlet going to the carb. When baler was allowed to drop the plastic flew up off of the outlet. (FYI on edit - previously there didn't appear to be suction at the outlet, but a retest shows there is.)

- Carburetor was removed, all jets cleaned (as per Don's video), and reinstalled.

- The fuel pump baler was been worked up and down a gazillion times and has yet to show resistance indicating the carb bowl is filled.

Q1. Would you happen to know what I should try next?
Q2. Is it a normal condition when the fuel pump baler is raised and suction is observed at the pump outlet going to the carb?


Thanks for any insight.
