The best way to do this would be to get a sensitive differential pressure gauge and hook it up between the 2 sides. There is a brand of these that I always have a hard time remembering: Helicoflex, or something that starts with Heli- That way you just have to watch one gauge, and keep the needle centered. For those of you with the dual balance pipe connections on each side, you may want to think hard about which pair to choose. I think 1 & 3, or 2 & 4, but not the diagonal combinations, because of the firing order (which is also the intake stroke order.) You mentioned that one side of your engine fell more quickly than the other. I wonder if this is a sign of a worn or misadjusted linkage. -- ******************************* Jim Adney, jadney@vwtype3.org Madison, Wisconsin, USA ******************************* ------------------------------------------------ To unsubscribe, E-mail to: <type3-off@vwtype3.org> For more help, see http://vwtype3.org/list/
