You guys are scaring me. I got this 85 jd318 that has the engine sitting on the floor. I have a rolling chassis as of now with only a few more parts to clean & paint. The po said it ran well when he dismantled the tractor. I was thinking about bench testing it to see how well it runs before installing it. Already learned some good points on here. Kenny that would definitely be a gem once completed. Will be watching closely just in case.
