So in the process of rebuilding the carbs and ski(had a blown motor) i notice that the small threaded hole for the idle adjustment screw is broken in half....

Its where #4 screws it on the diagram below.

Looking for suggestions here....

1. JB Weld it and try and re tap it?
2. Dont worry about it, the idle may be fine?
3. Try and adjust it via the throttle cable itself?
4. Chunk it and buy a used set for 300 or so?
