There is a threaded hole in the manifold to attach a vacuum gauge. You can get them on FleaBay. Example: http://www.ebay.com/itm/Carburetor-Valve-Fuel-Pump-Pressure-Vacuum-Tester-Gauge-Test-Kit-Car-Truck-/170971391604?pt=Motors_Automotive_Tools&hash=item27ceb06674&vxp=mtr#ht_3186wt_1039

Sylvan, I'm not really that well versed in carburetor repair. What is the instrument for measuring vacuum and where does one attach such an instrument on the A4's carb?

Date: Tue, 20 Aug 2013 10:01:11 -0700 (PDT) I've always used round toothpicks to clean jets, also useful to remove pilot/air jets, spray carb cleaner several times per orifice, and better use an air compressor. I still believe this is an air leak in the intake issue. A vacuum gauge reading without leak should show between 17 and 21 if I remember correctly ( with a steady needle ).

I have a later model A-4, and had very good luck with the rebuild kit from Moyer. As I recall new jets were included. Be careful as you remove them, as I recall a deep well socket was used to avoid breakage. I agree with others that anything beyond solvent (such as manually reaming or cleaning the jets) will probably lead to other problems. Been there, done that, not going to do it again...
