You can really use generic springs, even the ones you would
order from a supplier are likely some generic item that were
deemed acceptable.
Try to avoid using a higher-than-necessary spring tension, that
is one that pulls a lot harder than is needed to safely retract
the throttle.
Reason being, the sideways pull on the throttle shaft caused
by the spring is the chief cause of the SU-killing "throttle
shaft wear". Extra-heavy springs will accelerate this wear.
