OK, ive heard opels run hot, but i think my runs a little hotter than it should. according to the guage it is only 3/4 of the way to the top. is that normal, or should it run less. The fuel in my carb is perculating after I run it for a little while (10 min or so). I am missing the heat shield that is between the carb and intake. does anyone know where to get one? and is the fan shroud important for cooling? i noticed mine does not have one. 1 Last ?, when the fan is in motion, should it be blowing on the radiator, or pulling air through it? Any ideas would be appretiated, Thank you.
