I wouldn't trust any Huckel parameter combination for that kind of system

Ideally you should DFT. In case you can't run DFT anyways maybe you try in Huckel, the Cerda carbon basis set and the default for others.

Technically, your setup looks right. However, as Anders Blom noted, The Huckel basis set is not guaranteed to work well for this system.
