cold weather = hot plug

hot weather - med plug

30% fuel - hot plug

20% fuel - medium

30% fuel and warm temp - very hot

im not too sure if im 100% correct on those, id like someone to correct me if they know the actual answer.

and 30% hot weather to cold plug. Very hot with high nitro can be detonate if you don't know what your doing.
