Re: 57 evinrude question
When your twist throttle is wide open, look in the carb throat...the butterfly should be fully open. If not, do a link and synch. There is a key that mates the throttle linkage gears on those motors...if it's sloppy or missing, you can't get WOT. You can also adjust how it runs with the high-speed carb jet...if that's not set right, it'll be doggy.
