    Is it normal for this model carb to basically default to WOT on the shop bench?...i looked at the service manual and noticed that some pics do not have a throttle return spring on the throttle shaft. Seems like this could lead to a panic situation if the remote return spring were to ever break while an inexperienced driver were behind the wheel. It appears that the accelerator pump spring is the reason for this. Anyone ever see this? Thanks in advance

    Yes, how you handle the carb while disconnected can alter the accelerator pump linkage too.
    A doubled throttle return spring is recommended as a fail safe.

    Im no engineer but been a mechanic for a long time and i think its a b.s. design...this set up will wear out the throttle shaft bushings sooner than any other carb ive seen
