When you get your injector lines back from cad plating, take the time to insure that any residual debris in the lines from the cad plating process is purged.
A few years ago a member was tearing his hair out trying to diagnose and cure the rough running engine in his newly restored 250SL. I don't remember if the engine had been recently rebuilt before embarking on the restoration, but it was in great mechanical shape and running beautifully when removed and mothballed for the duration of his meticulous multi-year home garage restoration. Of course, all the cad plated bits were sent out to be redone.
He tried every trick in the book and more to cure poor idle, missing and lack of power. He knows his way around a Pagoda, but what had he failed to reassemble correctly? He sought and received guidance and even hands-on assistance from within and without the Pagoda community. Filters, solenoids, valves, timing, plugs, wires, pressures, linkage: everything seemed to be to spec and functioning properly.
Finally he resolved he might just have to bite the bullet and send his injector pump out to be rebuilt. While removing the injector lines he discovered tiny bits of debris at some of the injectors. He ran a length of derailleur shifter cable from a bicycle shop through all the lines, thoroughly flushed and blew them out, then had his injectors re-cleaned, flushed and tested. When reinstalled, the engine fired up and ran like a champ. Junk in the lines from the cad plating was the culprit!
