running higher nitro content= runs cooler ITS A FACT!
you cant just go up in the %nitro if your motor isnt shimmed for it. usually 20% is good but these smaller mills need a shim (usually) to run 30%. w/ higher nitro content it takes less fuel so you actually richen up the needle -so in theory you are running cooler. the plug makes a diff also.
