    I didn't read this or the other entire thread so you may have considered this. You said it seems to over heat while idling around, could it be the idle is too low on your motor not allowing the water pump to move enough water into the water jacket to cool the motor?

    What would make the idle too low and why would it have changed about march of last year? That is approximately when this issue started.

    scmoose, good thought! Occasionally, things loosen up over time, wires stretch, plastic fatigues, nuts loosen up. Look at the specs for that motor and see what rpm idle should be, then see where you are at. If you're below or on the low range of rpm's, kick up the idle to the high end of the range, at this point it couldn't hurt.

    Again Im not sure what all you have done but two different forums and multiple pages Im sure you have tried a bunch of stuff that may or may not have affected the idle. I would imagine there are a bunch of things that would do this, something as simple as the idle adjustments screw on the throttle linkage has vibrated / backed out, maybe a slightly restricted passage in one of the idle circuits in a carb, or maybe idle has nothing to do with it. Just suspicions that it only does it at low rpm / idle. May not do it on the muffs because you have added water pressure from the hose, If that's how you run it out of the water, to keep the pressure up at idle. Regardless good luck, I know these gremlins can be frustrating.
