I removed the MSD after installing the 1-2-3 Ignition and it’s been sitting in a covered box since.

I will take the Jim, I can pick them up any time you like.

You got it Bob

Thanks Jim, you're the best!

That setup works swell with a Unilite dist.

Exactly ! Before I installed the 1-2-3, there was a a Unilite. The 1-2-3 is far better; the optical sensor in the Unilite was a serious weak point.

If you hook up the Unilite backwards, you will quickly burn up the optical sensor/module. So, don't do that. And you might consider getting a spare module or two if you want to run the Unilite., while they're still available.

Also, the vacuum advance version of this distributor can fail in a way that might harm your motor. Probably best to only use the centrifugal advance version only. With that said, they really are awesome distributors, especially considering the time theywere originally designed.

Thanks all for the advice and insight. I will start looking into the spare sensor.
