You're right, Royson.

Long periods of inactivity do not always mean catastrophe, but I think the real conclusion that was reached above is that the chances of unforseen problems were increased beyond the buyers comfort level. I agree that perceived problems can't be confirmed without further investigation, but proceeding with troubleshooting or a pre-buy inspection when the first instinct is to walk away is almost always not advisable in a purchase. I can't find fault in following one's instincts on this, especially if you're not a mechanic capable of performing a few simple tests. Your experience level and mine might have yielded different results, but the chances aren't that good!

I can tell you from my own experience that for every good experience in restoring a neglected engine to service, there is at least one equally as bad! That's a 50/50 chance at best! Perhaps you (and Ken) were very lucky?
