1989 100hp motor not idling....

[Chief D78]

I have an 100hp evinrude and have just had the carbs cleaned but it does not idle smoothly and cuts off from time to time. It runs at top end just fine. Any help would be appreciated.

Have you checked Thermostat? It won't drop down to idle if the thermostat is bad or the thermal switch is bad

I think that motor has an overboard indicator on it.Its the small hose that leaks water.That tells you if your thermostat is open.If it runs when you start the motor the stat is stuck open.If it don't run at all,its shut and dont run the engine till its fixed.A lot of guys take em out,bad idea.
