Thanks for the replies. Yes, I reamed out the holes with a "special glow plug carbon reamer tool" that I bought from another online source (I'm an idiot for tools). Anyway, there seemed to be a fair amount of build up, but this was my first effort at reaming GP holes, so I have no comparison.

I tried to do more vacuuming than blowing, and even bought (here we go again) a nozzle attachment for my old Sears shopvac in an effort to remove the old carbon. The nozzle was still too big, so I don't know if it did much good.

I guess what I'm getting at is that I'm o.k. with how things are now after the full glow cycle. Again, this is my first diesel, MB or o/w, so I don't have any comparison. I suppose I had hoped that when I replaced the plugs and relay, it might glow-up, turn over, and crank right up, in a time-frame similar to a gasoline car, for example. However, this may just be the way an older diesel behaves.

Thanks for your thoughts.
