BUT.There is always a BUT.
You should check your temps according to ambient temperature.
Say the ambient is 50 you shoyldn't run the engine more than 220(MAX).If the air is 80-90 then you can go up to 250.This is to make sure that the engine it's not lean.Cause an engine running at 250 and ambient at 50 means that it runs leaner than when it's at 80-90 ambient.
Confused you???
