I can't say for sure with a 70cc, but this original honda 49cc kit I have on an nc50 express always has run hot wide open on warm days. Its a common complaint with cast iron Hondas. I suppose retarding ignition timing would help. A colder plug only seems to delay the inevitable high temps on mine.

When I took mine apart it looked a little toasty but the rings and landings were not full of crud.

What oil and mix are you using? How many miles on this?
