Cheers Craig
Has had new belt, rollers, spark plug, battery, ht coil, fuel tap, inlet manifold, variator, carb/jets cleaned during two recent services in last 6 months. No-one can get to the bottom of it stalling when idling - rides fine when power is on though.
From previous posts i have read sounds like the autochoke could be sticking on, but my local vespa dealer thinks not?
Any ideas?
cheers

There is a simple procedure for checking the function of the autochoke in the shop manual, IIRC.
If the carb is indeed clean and the gas is fresh, I'd wager the problem is either idle air/fuel mixture and/or idle speed related. Either would cause idling problems, but not have much effect on higher-speed running.
