I have a 1987 25 HP Johnson electric start with steering kit. When I start it up (in neutral), it automatically goes to full throttle. I know it has something to do with the idle knob and the throttle control. There is also a white plastic screw that looks like it stops the throttle from going to far. I am having trouble fine-tuning the various adjustment to make it idle at low speed. Can anyone help?
