Bosh AquaStar 125 B Natural Gas Pilot does not ignite

The pilot did not want to ignite in AQ 125 BNG, after unit was not used for 5+ years. The piezo igniter worked fine, just no natural gas was coming to the pilot. Turns out that there is a tiny pinhole orifice in the path of natural gas, that needed cleaning. I wiped the orifice on one side, and used a needle to make sure there was clearance. The pinhole is tiny perhaps as small as 100um.
