To answer your questions.#1 The carb isn't leaking and I have a six pack hood,the acc pumps work and doesn't matter how much fuel I pump into the motor. #2 I run 6lbs on the reg. #3 ignition is MSD 7al box,blaster coil, crank trigger and it's firing when I turn the motor over. The carb is a Quick Fuel 1050. The carb stays cool but the maifold runners at the head are very hot.
