I have a Losi XXXnt sport with the Mach .15 engine. I have ran appx 3/4 gallon of fuel in it so far. My truck runs great,.... accleration is great as well as the idel, but after I run the truck for appx 3 or 4 minutes it will suddenly die, ,and will be pretty difficult to start until it cools down. I didnt think it was too lean due to the fact that you could see the blue smoke trail on accleration. But the engine gets so hot that if you drip fuel on the head it will immediately sizzle to steam, and the aluminum chassis is even hot. Does it sound to be too lean and is there a way to tell if its overheating without buying an expensive temp gauge? And is there an affordiable temp gauge and what should b ethe temp range?

Thanks,
