chinese carb balancer fix

thingiverse

I've managed to score the most affordable priced lowest quality Chinese carb sync kit, it comes with four vacuum gauges but they're not even remotely calibrated to one another. The simplest way to resolve that problem is to only use one of them and this thing to select which carb you want to balance, that way the gauge will never need to be calibrated to another, you'll still need to check the lambda though. So print 5 barbs if you don't happen to have screw-in ones, you'll need 5 of those, and one of each of the other items. The barbs are glued into the main body and the top holds the selector knob in with 5 M5 screws, the holes will need to be drilled and tapped so the screws can get a grip, then it's a case of connecting lines to each carb and the single barb connects to the gauge.
