It's an 1985 300d Federal. The glow plug holes have been reamed the glow plugs replaced about 1.5 years ago. It starts fine at operating temperature. It has only had rough starts since blocking off the vacuum lines as described in my previous post.

The easy test here is simply plug everything back together and see if it affects the starts positively. I'm going to do that this week, although to my understanding it seems like the changes I made shouldn't have had an affect on the starting.

thanks
