Is it possible to fit a Tri-Spark ignition in an Atlas. I have the points driving unit in place of the magneto and have been running a Boyer for years. Is the Tri Spark a simple drop-in?

Yes, the Tri-Spark can be fitted to an Atlas with the points housing but needs to be the clockwise rotation version.

How's the reliability of the Tri--Spark? As good as the Boyer or Pazon?

Click to expand...

Early Classic Twin Tri-Sparks had some failures but the latest ones seem to be more reliable.

OK...I'm leaning in this direction once the covid money shows up
