Ohh ok, great! I have a failsafe, but I was told that if in some case where the power in the car would go dead, the failsafe would not work, therefore I should use a throttle return spring to force the carb close. The day before yesterday, my failsafe safed me from a runaway, I checked the batteries in my truck but they were still 40% charged.

Is my failsafe maybe that good that it engages when the battery is low, so I won't have to worry about runaways?
