I have a 1990 evinrude 25 that I have been working on this summer. I have the engine starting and running good, but I cannot get it to reach full throttle using the lever on the control box. When the lever is in the upright position, the butterfly in the carb is closed, as it should be. When I start to move the lever forward, I have to push it almost all the way down before the throttle begins to turn the butterfly. When the lever is pushed as far as it will go, it will only open the butterfly about a quarter to halfway. I have played with all of the throttle linkages on the engine and carb to no avail. By adjusting them, I was able to get it the butterfly to open all the way, but when I achieved this the butterfly would still be partially open when the lever was in the upright position. It almost seems as if the control box does not provide enough throw. Something else worth noting is that the warmup lever must be engaged to start the motor, but lifting it does not affect the RPMs at all.
Any input or tips would be greatly appreciated!
