I recently had to change engines in my 79 450 SLC. The "old" engine was a rebuilt 450 SL engine with only 43xxx miles. The party I bought it from moved to CA and I have no way of getting in touch with her, I only know the work was done in Texas.
In any event, the "old" engine was very difficult to start when it was warm, cold it started instantly. I have exactly the same problem with the "new" engine, a 450 SEL engine with 113xxx miles.
Has anyone else experienced this problem and if so how was it solved. If it occured on only one of the engines I would suspect one of several things, but happening on both, I ahve no ideas.
I live in the Missouri Ozarks (a great place to drive one of these cars) and am over 100 miles from the nearest MB dealer/service facility. Any ideas would be greatly appreciated.
