hello,

i dont get what do you consider hot or too hot? how high is the temp gauge getting? i'm pretty sure that the marks on the temperature gauge are in 20 degree increments , and i'm pretty sure that the normal operating temperature for the m103 is 87-90 degrees celsius.

so... if the temperature needle is between the 80 C and 100 C marks, that seems like its normal operating temperature.

ps an engine runing at less than normal operating temperature 90 C is not good, for a number of reasons.
