Just in case anyone is interested I found a guy to work on 220s. His name is Craig Nelson
Briefly, I approached him about working on a 220 and, after a week or two of mulling, decided to take on the task. He had never worked on one before.
Cutting to the chase, he did a major engine-out service and all’s well. New cam belts, water pumps, fuel pumps, clutch, hoses, fuel system overhaul, new fuel tank, and so forth. I can’t even remember it all. The car has never driven or sounded better in my memory. I haven’t scrutinized the work in detail but on brief examination everything looks good in terms of workmanship.
Craig says he enjoyed the work and would be happy to work on others.
If you’re looking for options give him a call.
