ok so my 3.3 is giving me trouble and driving me insane. saturday i went to a track and drove. truck ran fine til the end of the day, then she started running hot. the next day i went to the park with my buddy, and the truck was running hot right off the get go. 290-310. kept trying to richen it up and it just wasnt helping. had the hi speed 6 turns out. the exhaust header broke off, so i had to quit. put a new header on, reset carb, and still had problems. once again, i started making it richer. no matter how far in or out you turn it, the temp stays constant. i scattered the carb and blew it out. clean as a whistle. also cleaned the tank. added new fuel lines. checked everything i could think of. and again, it still ran hot. so what do i do? and the motor is fairly new. about 1 and 1/2 gallons run thru. thanks for any help.
