It's fine. 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.
