<DIV>Could the airflow not be the same between the 2 planes to cool the pump and engine? Is the exhaust clear of carbon deposits in the header(my own experience). Look at what is different between the 2 planes. Seems strange it was running well, different plane, and then bad. Try putting it back in the original plane, if the problem goes away, it is somewhere in the #2 plane, and not the engine.</DIV>
