Page 157 of the 94 parts list 56355-92 idle control and 56356-92 throttle control both seem to be good part numbers and available here in the uk but your dealer parts specialist should have been able to find that for you
Is it a stock carb or has someone changed it?? Sometimes with a different carb you have to reroute the throttle cable. Just an idea, but would have thought dealer tech would know this.
