Hello, I recently have inherited my grandpas 9N tractor. It use to run like a champ but has been on much lower duty for a few years now. After a closer look after a failed starting attempt I noticed a few things. I have a Zenith carb on it, not the M/S carb. I get gas all the way to the carb but it wasn't firing today. I also noticed I will probably have to work on the starter as well. I'm not sure if the starter issue is leading to this, but it seems like the tractor started to turn over harder than normal today (battery is good.) Any info is helpful. Thanks.
