footbrake racers

yah it was a number of things for me... parts not all matching up completly.. timing.... carb cutting out from bad fuel... almost every worst case scenario. but we race in bakersfield only really were its almost always over 100 trackside and sometimes 120 on the track so i need to dial the car in for those conditions.. weather is similar were i live but were i take the car out to most shows are by the beaches and its nice 75-80 degrees year round haha.
anything carb and tuning wise for hot weather i should be aware of?
