Redneck carb test stand

That WAS water you were sucking into your vacuum wasn't it?
Negative, I'm a bold one. It's my shop vac, so I don't care if it gets some gas in it. That, and I had it filled with sand to absorb the fuel that did get sucked into the vac.
auto prime leaking?
This is a chinese carb off of a roketa dune buggy. They drilled the holes for the intermediate circuit wrong, and if the throttle blade was open just 1 turn on the idle screw, it was pulling from the intermediate circuit. So I drilled a 1/16" hole in the butterfly to allow it more air with the throttle closed so I could adjust the idle mixture. The other problem with it is that the orifice for the primestart is to large for the fuel side, and it floods when the primestart is open. This thing is just a fine example of chinese crapmanship. He has complained about how this buggy has run since new, and it all has been carb problems the dealer wouldn't fix. Other than having to hold the throttle open when it's cold until the primestart closes, it now runs awesome. I hate having to find machining errors, and hate even more having to find solutions to the machining errors.
