I am having a funny problem with my 1963 Evinrude 40hp.<br /><br />After a lot of work and diagnosing I have managed to get the motor to run on both cylinders(earlier problem), but It is still turd slow in the water. We took it out a week ago to test and came up with this.<br /><br />It has a really unpredictable throttle. Sometimes at a 1/4 throttle it will go like 3/4. WOT always bogs. Then I'll give it just s bit more and it boggs. I felt it pick up ONCE so I figured this has to be a fuel problem.<br /><br />What I have done:<br />1)lots of debris in fuel bulb, so ordered a new filter and cleaned pump.<br />2)Decided to rebuild carb, found out that everything inside looked clean, did it anyways.<br />3)Fuel tank is new and lines to motor are new as well.<br /><br />What I haven't done:<br />1)check fuel lines and replace.<br /><br />Anything else that I am missing? The leaf plate and leaves look perfect. What about the hot water choke... or something else???<br /><br />Thanks Guys
