Interesting occurrence, at least to me.
Reconnected the O2 and fuel lines etc. Hit the starter engine started fine ran a bit rough but not to bad. Then shut it off intent on doing more tomorrow.

Then looked under the seat and realized I had not plugged in the OXS ECU connector!
Funny I would have thought it would not start or run with that not plugged in but it did.

Plugged it in and restarted. Ran super smooth but I have not heard it run for a few weeks so maybe that is why it sounded so good.

Tomorrow I will do the AEC test as suggested by mysocal911

Thanks again for all the troubleshooting help. All of you be well and stay 6 feet apart!
