Sold the 8N I had been working on. Never did get the smoking issue resolved. I listed it on Craigslist as a smoker and priced it accordingly. The first gentleman to look at it bought it. He has mechanical skills and was not concerned with the smoking issue. The tractor was in great shape otherwise. Still I hate to part with one after doing so much work on it and I have no plans for bringing another one back in the future.
