"okay, this is grasping for straws... but i am out of ideas. are there going to be different numbers for water temp. and cyl. head temp.? looking at the t-stat it is measuring the water temp and where it is coming into the motor, along with the heat sensor, checking water temp at the top of the motor where the water comes in. my temp. gauge is measureing cyl. head temp and i have it connected between the two cyl. and i know that the bottom cyl. usually runs hotter than the top one, further from the cool water coming into the motor. so now i am wondering, is the temp that i am looking at going to be higher than the water temp numbers i am comparing them to for a normal operating temp.?? if not, do you have any suggestions what i should look at next... heat range on the plugs hasn't changed, the plugs burn clean but aren't white or light gray like it is to lean, the fuel-oil mixture is always exactly the same. there is nothing to indicate that there is an air leak, leak down test shows top of the good range. there is no way to test the water pressure , but the impeller is new and there is water coming out of the tell tale. i'm stumped??"
