I have put the car back together on Saturday and started as soon as fuel got into the system. Joining the timing chain is not for the shaky hands in case the linking pin drops down the hole unless proper precautions were put in place. Car runs well and responds to gas quite promptly.
Now I eliminated the broken airflow housing for the idle/cold start problem I can go with the OVP next Sat. Thanks to the forum for all the tips I acquired along the way.
