I dont even have the body on the truck at the time of running it. But i will try to seal the carb and the backplate, is there a cerrtain kind of sealent or brand that you could suggest. And how can i check if there is a fuel leak, I can hold the truck upside down and no fuel leaks out from it. And sorry i was being a little impatient, it is just very frustrating having the hsn as rich as rich can get and the temp dosent go down at all.
