Fixing to start putting motor back in frame after complete rebuild. Will the oil injection pick up oil once the motor is running. Will bleed air out of line before hooking back up .

It should, just follow the bleeding procedure in the owner's manual.

Also, I think it is a good idea to run premix on the first tank or two of fuel anyway. The extra oil may or may not foul a plug or two (less likely with synthetic oil) but at least you will be assured of lubrication in case a bubble of air that you didn't see goes through.
