We are all familiar with the Rotax 912 throttle springs. Note that where they hook into the throttle lever arm, there are little plastic sleeves in the lever arm hole to prevent wear. There are two different sleeve sizes, part numbers:
963015 - on the Throttle Valve Lever (Top of throttle spring)
963010 - on the Cable Support (Bottom of throttle spring)
There is a similar spring on the choke (starting carb). However, it does not have a little plastic sleeve fitted. Nor do I see one on the diagram in the Illustrated Parts Catalog. The top of the spring goes into a pretty sturdy place on the Chamber Top. But I am noticing a tiny bit of wear from the spring hook (bottom of spring) to its hole on the Choke Lever arm.
Anyone else see this?
Should we retrofit a sleeve?
If so, which sleeve type (if either?)
Or another idea?
