Does anyone have a detailed drawing of the water pump assembly for this motor, model 4443, neutral clutch? i need to see how the water inlet pieces are assembled. the impeller seems ok, but it won’t pump in the test barrel. Also what are initial carb settings for this motor. ( I am getting ready to sell.)
Thanks,

That is a Tillotson carb on that. Low speed is about 1/4 turn out and high speed is about 3/4
The low speed needle on these is an air bypass, rather than a fuel flow (like the later Fleetwin carbs.} Evinrude used the Tillotson carbs on the Fastwin models through 1952 and 1953 on the Fleetwin.
Can we assume you have the correct impeller? Hint: The pump sections are all keyed together and must be aligned correctly. The flat spring underneath holds it all together.
