When you say expect it to last for only a few gallons do you mean thats all it will last then you have to buy a new one or you will have to rebuild it?

Tune your engine to run the way you like it, then adjust based on the temperature readings you are getting.
Fuel Brand and % of Nitro can have a large impact on needle settings.
Pops,
I try to get my engine around 220. when i run it out in my street it usually keeps between 220-235. usually no more than that. I try to run it full throttle several times to see how high the temp is. But i was racing last weekend and after a 5 minute heat i checked the temp and it was 275. When i run i usually run after 5:00pm (time i get off of work) but this race was run in the morning and throughout the afternoon plus i had a black body on. Could this have caused the radical temp change?
