Sorry if this has been posted before,
This is my first time and I did a search and came up with nothing.
My Vespa will not return to the idle stop pin Even when I manually turn the throttle grip.
The only way to gain idle is to get into the tub and physically turn the throttle wheel by hand back to the stop pin.
This is causing the scooter to run away if the brakes are not applied.
I have search for 2 days for a solution and done a few checks and can't find a solution.
Tried to lubricate both ends of both the push and pull cables with silicone oil but nothing seems to help.
I can see that the scooter must have the cruise control as the grip does not return on its own. I have checked the slack on both cables and it appears to be ok.
I just cant see why the throttle will not return to the idle stop.
Any suggestions will be more than welcome as this issue has been a re-occuring issue and has required a shop visit twice which resolves it for a few months then is back so I would love to be able to fix this with out the shop visits.
