Inconsistent CIS starts

[ohecht]

Recently rebuilt CIS on an 82 SC, and the start behavor is not quite the same.

The car used to always start on the first crank, to the point I barely new what the starter sounded like.

Now, it will fire up like that first thing in the morning with a small puff of white smoke, but starts after that are less consistent.

Even after 8+ hours of sitting, it can take 2-3 seconds of cranking to start. When the engine is still warm, it could go either way.

I assume the white smoke is from some fuel that maybe puddled at the intakes overnight, but I would assume the same thing would happen after 8 hours.

All fuel pressures are in spec, altough the residual pressure is not as high as it was before the rebuild (still in spec, though).

Thanks,

Olivier
