So I just purchased a rebuilt carb for my mercruiser inline 6. Question came to mind after messing with choke all day. which I still can't get right. Is this mallory rebuilt carb suppose to have a stepped fast idle cam like automotive style. I thought marine carbs have a smooth cam. So with The choke plate is closed cold boat starts right up. revs out to about 2000 rpm so then i snap throttle knocks down to about 1500. Then I had to adjust it so it would idle around 700. let boat sit for 1 hour go back starts right up idles at 750 go to hit throttle goes back up to 1500? There is 4 steps on the fastt idle cam is this correct? What am I doing wrong.
