All of the 150cc models used the beautiful "clamshell" speedometer which was also used on the G.S. The 150 had a "Vespa 150" badge riveted to the right side of the legshield. The Vespa and Vespa 150 badges were made of flat aluminum. They had a similar layout to the later motors, but were not rotary valve. Bottom LineThe Vespa 150 is a robust scooter and capable of use on today's roads.

DescriptionFlywheel Vespa VNB/VBB/GL/VBC/Sprint and more (94733) with Metal Fan. Must use "TOOLFLY26" for removal and flywheel nut 012066. This is all you can get these days for a flywheel for VBB, GL, Sprint, Super that will work with points style ignition systems. Original vintage look with detachable metal fan. They are made in India, but they actually work really well and have strong magnets.

The upper bulb on the bike is the brake light, which is the bottom bulb on the schematic. You've confirmed that there's a good ground connection, so now it's time to sort out the problem with your switch box. Could you post a pic of the back side of your switch box so we can see what's connected where? Yet according to your earlier post, the brake light only works when high beam is engaged. The only way this could happen would be if your bike isn't wired according to the schematic you've posted.
So i've i've done the following in order:- Cleaned tank + replaced fuel tap. I'm doing the following:1) Remove spark plug and install piston stop tool (which I ordered from scooter mercato). 3) Turn flywheel clockwise to piston stop. 5) Turn flywheel counter-clockwise to piston stop. 8) Remove piston stop tool and rotate flywheel to 0 on the disc at the pointer.
