My 1983 Johnson seahorse 25 has a horrible hesitation when idling but not when running full throttle. It also hesitates for about 1-2 sec when u put the shifter from slow to fast. It is mixed 50:1 with premium fuel. Has new carburetor kit and such. The only thing is where the throttle cable connect on the left side there is a lot of play from being worn out and old. Also when I put it in high idle with the separate control it dosent rev up to much faster. You can move the throttle about 1 inch more on the motor head to where it is supposed to be at high idle. Also how do I set the timing on the motor without a test wheel. I believe this is my hesitation. I would take it to a marine shop but I don't want to have to cut my leg off to pay the bill. Thanks, Mahanoy

You can set idle and pickup timing without a test wheel, start with that.

There is only one throttle adjustment and there is not much of an adjustment you will see the linkages on the starboard side.

You should be able to run through the full rpm range in a 55 gal drum. Do not put into gear.
