Twatwaffles would be appropriate.
The OP asked a reasonable question. Believe or not, there have been hundreds of thousands of shifty Vespa owners who are not interested in receiving the admiration of smart ass wrench turners.

Red is probably 2T oil. There are a variety of problems that could result in such a leak. The oil tank, feed hose, carb gasket or air box gasket. If you are reasonably handy with handtools, then get your hands on a Haynes manual for the PX and take a look at the items I mentioned. As is the case with most fluid leaks, very often the visible location of the fluid may not readily identify the leak site itself. Gonna have to look at the system elements.
Good hunting and feel free to yell for pointers.
