Re: Still having heat problems :(
Even if the plug looks good, it may be worth trying to richen it up a little, the extra fuel helps cool the engine. I'd try raising the needle one notch and see if it helps. What's the worst that can happen? Your MPG might go from 150 down to 140 and there's a chance you could foul the plug. I'd say it's worth a shot if you don't have any other ideas, I can touch my engine for a second before i need to pull my hand away so your sounds really hot.
