    I just bought a Ford 9N. It runs like a dream, but it seems that the top end throttle rpm is lower than the engine is safely capable of. I have 3 questions. Can I increase the rpms by adjusting the carb? If yes to question 1 how? Question 3 is how high is safe, and short of bying analyzing equipment how do I tell?

    Get a T & I Manual. They sell them at TSC, it has all the specs and some maintainance procedures, 2 of which are carb adjustment and governor adjustment.

    You adjust the governor/throttle linkage and not the carburetor.

    You can get the rpm higher that are suposed to be acording to specs but you run the risk of engine falier at the higher speds. The 9n is an older tractor and the engine probily won't be to facory spects but if you run it too high you may like it for a while but the engine will wear out faster.

    www.ntractorclub.com is also an ecxellent site with a good deal of info. I t also has a great following in the forum and those folks know their old Fords inside and out. I have a '47 8N and use the site time to time for trouble shooting. Never ceases to amaze me, I can tinker with a problem for days before posting a question and usually get the info I need in a matter of hours. Good luck, Paul.

    Congratulations on your tractor purchase. You need to purhase the manual and you will learn how to adjust your governor. Try this board for good N series tractor info: http://www.ytmag.com/nboard/wwwboard1.html

    I have an early 8N and it is the single most useful piece of equipment that I own.

    I have a '42 9N. It too runs at what seems like low RPMs compared to newer machines. But.... it is 64 years old and is still a good runner and worker. Might be some correlation there (low RPM and long age), ya think?

    countrymech, if you have a 1947 ford tractor you may not have an 8n. There are a few transistion 1947 tractors but they are scarce. Have you done any research on how the 2n, 9n, 8n series were named?

    Agmantoo, once again I stand corrected. I went back out and looked at the casting numbers and they indicate D228 8N, April 22nd 1948. Good catch, don't know why I got twisted up on '47. I thought I would have remembered more accurately after having rebuilt the damn thing a couple of years ago. Sorry 'bout that, Paul.
