Here is the issue, fast idle cable is not working. When I "engage" it, cable appears to be slipping by the lock nut at the engine. There is alittle movement on the arm at the engine. Therefore I believe the cable is not broken. I know I need to remove the seats (easy). Need to remove gas tank also to get to it. My question is this, are there any sort of check valves or shut off valves on the tank so I don't have gas everywhere? Should I remove gas from tank all together? Any hints or ideas to make job easy will be greatfully helpful. Thanks in advance!
