Thanks Bruce, good communications, gives me a better picture. It should seat fairly secure and not wobble too much. It si difficult to judge without being there. You said when it's lying flat and you turn it, you don't hear any scraping noises and it seems to turn freely.
My last suggestion is to call Fabio at the Vespa Super shop in San Diego. He has been working on these things since the italian army surrendered in WW II (don't tell him that or he'll open a can of Italian Woop Ass on me). His number is 619-574-1818. He dosen't do email but he is an expert on this stuff. Remember the time zone difference. He opens at 10 am PST.
I do find time to ride in the winter months when things slow down a bit but this year the demand hasn't let up. I go riding with my son Wes who is 16 1/2. He loves to outrun the old man with his Suzuki OR50 (50cc, 5 speed, 60 mph).
Anyway good luck
