1920 D/A - 20 HP Kohler- new gas filter, new air filter- runs good for a bit then acts like it runs out of gas ; choke it , it pulls it thru but not up to top speed- theres a box looking thing / pump that the gas line is connected too - before the carb- any numbers or info on this ??? Thanks!!

Disconnect the existing fuel line between the fuel pump and the carb. Connect a new line from a test tank to the carburetor fuel inlet. Fuel the test tank with fresh gas. The described system bypasses the existing. If the engine runs out fine, then you likely have a restriction of fuel flow or a dying pump or both.
