Those old 621's could be tough to start even when they were new.

I think the biggest problem is the starter does not turn it over fast enough.

I am 90% sure that a starter from a 300D turbo would fit on there. Perhaps someone on the vintage forum could confirm or deny that.

Keep an eye on your compression. From 68 on, there was some bad metal in the engines for a few years. Cylinders would out egg shaped. I think most 67's were OK, but I don't know exactly when that problem started.
