Hi all,
I stumbled across an interesting plug reading article covering mixture and ignition timing. Here are my plugs from #1 and #4 cylinders.
the run mix looks OK (to me), the black on the electrode and the end of the threaded portion indicates a rich idle (per article). The location of color change on the ground strap seems to indicate my timing is too advanced (per article)?
I sure would appreciate feedback. I am running a pertronix but switching back to points (my TR6 unit died after ~9 years). However, I'm afraid my distributor has way too much side-side play. Is Advanced distributors still our best bet? I saw were jollyroger was selling a new Lucas made 25D4 for a MGB...could this be used? I have a Lucas made bushing, but I'm a bit concerned about damage to the body of the distributor? What's the best option for an old worn out distributor?
TIA for any feedback
Tim
