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.
