That is the factory spec. The TBI engines with swirl port heads do not like a lot of timing. You can cheat it ahead a few degrees, maybe 4 or so, but no more.

Be sure to disconnect the bypass wire when you set your base timing.

TBI are set to factory, mine @ +4, and the dist automatically advances as you drive.

At my smog inspection, the computer tells the operator what it is set at. Any more than 2 deg off & you fail.
