Tim, thanks for the comments. My other Series is a 1962 which I have had for over ten years now with little to no problems, however, it was rebuilt while I was in Switzerland by a pretty unique shop that only restores Series and kits out 110s for expedition(they really knew what they were doing) so I have probably been spoiled by its reliability. The 1972 with the problem(s) that seem to mount I bought as more of a daily driver and to use for 4-6 hour round trips. I am definitely in it for the long haul but want to make sure I do not keep patching a problem that will have to be replaced eventually. Scary thing is I was actually convincing my wife the need for a Series 1 on ebay that was up for bid the night before the break down.
