Don't worry about it at all, but you might drip some oil in there to lube the shaft since the starter fluid may have washed the shaft clean. Our FI, unlike most other FI systems, meters the fuel based on the manifold vacuum, so any air leaks are accounted for in this measurement. The only air leaks that might be important are those in the hose to the vacuum sensor, because these would give a false measurment, leaks in the sensor itself, for the same reason, and leaks at the heads which would make one cylinder run leaner than the others. -- Jim Adney jadney@vwtype3.org Madison, WI 53711-3054 USA ------------------------------------------------------------------- List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org
