Keeps getting to hot

What's your total timing ?
What carb/jets (lean condition) ?
Antifreeze to water ratio ?

Water wetter will not do a thing with a 50/50 antifreeze/water mix.

For the summer go to a 80 distilled water/20 antifreeze mix with water wetter.
Adjust total timming to 34 degrees.
Try these two things first. Made a huge difference for me.

Next step...Possibly fattening up the carb.

Another thing I did,was remove the front lic plate.
