Having trouble with my 720 going into drive. truck will start and will take forever to warm up, have to press the gas pedal to lower the rpms after about 5 mins. But soon as i put into gear (reverse or drive the truck shuts off. ive tried checking time, adjusting the rotor cap, adjusting the fuel on the carb and nothing works. Damn near about to drag it to the demolition range slap some explosives to it and trial by error with my fellow 12Bs figure out how to dismantle it with one shot...
