My 9N which I purchased a few days ago starts, but goes from idle to full throttle in just a small amount of throttle movement. Likes to start with the throttle fully closed or just barely cracked. We put seafoam in the gas and ran it for awhile, but that didn't help. It hasn't been used much which is why the guy sold it as he was tired of working on it and he hardly ever started it. My buddy and I are planning on pulling the carburetor and governor and giving them a good cleaning. Open to any advice from folks who have any suggestions/advice.
I just finished reading "75 tips for N owners" and found it a great resource. I have hundreds of hours on a 9N and 8N, but that was 43 years ago and dad did most all the maintenance. I'm looking forward to going through this tractor with my friend who likes to work on old tractors.
