I have not tried this because another guy did that on this same moter and got water in the mixing elbow, which in turn got the injectors wet. I agree this may be the problem given my previous troubleshoting steps.

FarCry, I have tried leaving the slip and it seems to overheat even more rapidly.

Thank you both for your input.
