Re: stumped 1972 25hp evinrude
Here's something to check jethro.....
Look up in back of the carb and you'll see a lever with a roller attached. You'll also see the cam attached to the mag plate.....on the cam should be a reference mark. Roll the twist grip and watch the cam come around to the roller. When the mark is centered on the roller, the throttle plate should just start to open. If it needs adjustment, losen the 5/16" bolts that attach the cam to the plate and move it in or out until the above adjustment is made.
