Carburator Syncing Device

As I will need to synchronize my carburetors after doing the valves I looked around for the tools I would need to get the job done.  I found I would need a way to measure the vacuum of the carburetors   I found a DIY over at ninja250.org and followed the directions on this page.

Here is what I ended up with.

I used blue food coloring just to make sure my seals are air tight, but I'll have to use green for the real deal.
