Here is what ya do , the one guy has coved the basic's But let me add to . If you are running a HOT spark plug get rid of them and run what it calls for next make sure your load screw is opened for full load work do a Major tune up like he said valve adjustment , ing timing and check what she is doing at full throttle as far as full advance . Check the dist. for broken / stretched advance springs and here the BIGGY change your gas todays gas is NOT the gas they were designed to run on , i have been down this road with the Farmalls of the era and once you get past the 460-560 you are screwed big time as now we as in all of us around here can NOT get gas that will run them on . You have no real history on that tractor as to what all has been done to it or how many times that head has been off and milled down and each time you take off to flaten it you raise the Compression ratio and as compression ratio goes up the need for higher octane fuel increases. Reg gas for the day when new was a Minimum of 93 and MOST reg gas at the gas stations was 95 and ever the OLD gas semi's had to run 105 or better , yea i drove one of them old gas semi so i know what they needed and the gas pumps at the fuel islands in the truck stops was the good go go juice as it would even run in my 61 Ford with the hand built 390 tri power that started from a new bare block and bare heads . YOu can try the 89 octane and see if it helps then what they call the 93 and see how that works . With darn near 60 years of engine building under my belt i have a little bit of knowledge on this .

Today's Featured Article - The Day Mom Drove the 8N - by Brian Browning. My Dad was wanting to put in a garden but couldn't operate the 8N and handle the old horse drawn plow he had found and rigged up to use with the tractor. Well, he decided to go get Mom out of the house and have her drive the tractor while he walked behind the plow. You got to understand that while my Mom is a hard worker who will always help whenever she can... she had never operated farm machinery before that day. Dad got her out there, explained how the clutch was the same as in our o
