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. | | | Re: timing settings | Joined: Jun 2010 Posts: 18,308 Likes: 569 | Joined: Jun 2010 Posts: 18,308 Likes: 569 | 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.
