Well, I got the tiller out and cleaned up a bit. After a little TLC, and cleaning the spark plug, it cranked right up. However I found a problem. It looks like the throttle cable was replaced by someone incorrectly, and it won't respond to the throttle control on the handles. I'll post a photo tomorrow to see if anyone can give me advice. I can't find a photo of how it's supposed to be online anywhere. It runs pretty good, just in idle. If anyone has any thoughts, I'd appreciate them. I'm skunked. Apparently, there are a lot of configurations of Tecumseh 6hp engines, but few illustrations on a HH60 engine on one.
