I have a 1978 Evinrude 85 that starts pretty good, seems to take a not unreasonable amount of time to warm up, and runs pretty well at high speed.
It seems to idle lower than it should though, and after it warms up, it doesn't seem to want to idle at all without useing the warm-up lever. Its a little tougher to start once it warms up too.
Messing with the thumbwheel on the throttle cable doesn't really help.
I figure I need to adjust the low-speed needle valve. That leads to my question. Thier aretwo little screw caps on the sides of the carbs that, once removed, reveal little screws inside. Are these the low and high-spead orifice adjustments?
If so, how would I adjust the low speed orififices? Since thier are two (one on each carb), how do I know which one is out of wack when I start adjusting them? Seems it would be easy if their were just one carb, but I'm not sure how yould do this with two. Do I just pick one, mess with it until its as good as it gets, then do the same on the other side?
If these little screws aren't the adjustment I'm looking for, what is?
