Update for anyone following. Definitely a mechanical issue from the rebuild and they will be pulling and hopefully fixing. I can only hope that they take good care and that things go smoothly. I am promised that I will get it back fully functional and test driven. They have extended the warranty to three years/36,000 miles. It's not a free option for me but saves two tows, me removing, transporting, reinstalling and then towing back for first fill and start. I wanted to use that extra $$$ for a steering wheel, welder and lots of new rubber parts. I would do it but am about to get very busy on rental rehab. Oh well.
