adjusting throttle and linkage on amerc

[andy 1]

Looks like my questions never stop now that I have my motor height fixed, I need to know how to adjust my throttle and shift linkage, the motor is a 1987 merc tiller pull start. Prblem is when I want to go fwd I turn the tiller handle almost a third of a turn before it engages into gear and then it goes fast, very poor slow speed

thanks
