Bill, the only thing I can think of is to check the sealing around the
edges of the coolant radiator. The air needs to go through the fins not
round the sides. Also, the ratio of the exit for rad and cowling may have a
bearing on it. Too much air escaping instead of going through the fins.
Have a close look at the ones that work and compare with yours. Then do
some hard thinking. Sideways as well as plain logic. Logic can lead you
down the wrong road.
