1983 15hp evinrude carb adjustments

[jspano]

i have a 15 hp 1983 evinrude. there are 2 knobs on it 1 on the side by the tiller i think its the low idle and another up front by the choke i think its the high idle air adjustment.
i'm having a hard time starting it, is there a starting adjustment on these to get it started, like turning it all the way in and 1 1/2 out.

The knob on the side is the idle speed adjustment.

The knob on the front is the idle mixture adjustment

I think there is a problem with the idle speed adjustment and you will find something about it HERE

The basic setting for the mixture screw is to gently seat then screw out 1? turns but see Joe Reeves' instructions on the Engine FAQ board http://forums.iboats.com/showthread.php?t=167352
