Well, after the big scare with the gasoline spill and my fears assiciated with it my 8N is purring like a kitten again. Prior to the now infamous "spill" of gasoline I was having a couple problems. First the governor did not seem to be working right. When I would change positions of the throttle lever, the engine was very slow to respond if it did at all. I had to get off the tractor and manually move the throttle arm between the carb and the governor to achieve the desired rpms. Figured I was looking at rebuilding or replacing it. Second, despite repeated attempts to adjust the carb, the engine was still sputtering at high rpms. After the gas spill I did the following things:
1. Pulled all four plugs. After gas odor was gone I cranked the engine (ignition off) a few times. I checked the gap plug and found that two of them were gapped at .o30 and the other two at .028. I re-gapped them all to .025. 2. I removed and disasembled the carb. Completely disadembled it and thoroughly cleaned it. 3. Changed the oil due to strong odor of gas on the dipstick. (I had just changed the oil a couple months ago and had only put about 1 hour on the tractor since then.) After replacing the plugs and the carb, I cranked her over and she started right up but was running quite rough, sounded like on three cylinders. I adjusted the idle and main jet screws but still was running rough. After running for 2-3 minutes and a couple pops she started purring like a kitten. I noticed that the governor was working perfectly with immediate response to changes in the throttle lever. I can only atribute it to a gummed up carb, I noticed that prior to cleaning the carb, the throttle shaft was difficult to open and close by hand, but after cleaning it was smooth and easy to operate. I assume this is why the governor didn't seem to be working, just couldn't fight the built up gunk. Thanks to all of you who responded to my questions and concerns. It is amazing how a smooth running tractor makes one's perspective more positive.
