Skyport was selling copies of the Stromberg overhaul manual which had the
information you are seeking for the vent re-location.

However many cases of Strombergs leaking are due to needle and seat issues.

I understand there is a service Bulletin for the bendix/Stromberg NA-S3A1
caburetor regarding rerouting a vent or bleed air source to stop fuel
leaking. Ring a bell with anyone or do you have a copy?
