Carb set up 1989 50 Hp

[tiller7104]

Hey guys, 1989 50 hp just took carb apart and cleaned it and for got to do one very important thing!! I did not count how many turns that my needle valve took to remove it. Any sugesstions for a good starting spot? The old rule of thumb used to be 1 and 1/2 turns out but I do not know if that applies here. Once I get it running what am I looking for in the fine tunning? Sound, smoothness, not real sure! Thanks again for all your continued help and support. Stuart

Idle mixture screw starting point, 1 turn out, from lightly seated.<br /><br />If too lean, motor may sneeze, or will die when you accellerate: turn it out another 1/4 turn and try again.<br /><br />If too rich, plugs will foul.<br />Just right, or a little on the rich side, and motor will stumble then accellerate when you gun it.<br /><br />Better rich than lean.

I am having trouble keeping this motor at idle? I have cleaned carb out good needles, seats, jets etc. Is there anything that I can do to the carb to rectify the idle problem?

Do you have a tach?<br />Idle speed may have to be bumped up a bit.<br />800 rpm is good.
