Well I am not the local Deere GURU but i see the low octane fuel has now jumped colors . I can tell ya that you were using 87 octane gas and that is way to low on a gas tractor that is trying to be used in the manner that it was intend to be used . As for your friend's 544 that is what happened to his as he had a piston start to super heat and started to gulled to the sleeve or wall , you had the same thing happen . Now as to any damage done to the inside of the engine well with out pulling the head i can not say for sure but there is a good chance that you did . I have perched about this on the I H board till i am blue in the face as the tractors of the late 50'- the last of the gassers they were ALL made to run on nothing less then 90 octane and I H's were made to run on nothing less then 93 . Now from what i have learned from a Chemist and i am by no means as smart as the guy that did the fuel testing when we had a new engine with a little over 30 hours melt down and when i opened up that engine and my knowledge of engines i could tell that she got HOT and real fast to start to melt the top of the piston. or in this case Pistons as it got all 6 . So with what you are telling me that she was breathing heavy out the breather then there is a real good chance that you hurt her big time . And like i tryed to explain it last week that yea 93 octane gas is 20 cents a gallon more at the pump the total cost per 200 gallon over the 87 is a lousy 40 bucks and it will take a lot of 40 bucks to fix what went wrong to just try and save a few cents. You will never see this heat on the temp. gauge as it takes a long time to soke into the coolant to show up on the gauge, Case in point here look how long it takes for the water to warm up but just try and put your hand on the exhaust manifold 30 second after ya start a gas tractor .

Today's Featured Article - The Rescue of a Fordson F - by Anthony West. Introduction I live in the UK and have for many years restored Fordson tractors (in the main model N's). I have also restored and shown model F's, E 27N's, Field Marshall Series 2, David Brown Cropmasters and the old rey Fergeson T 20. At one time I had seven restored examples which were shown and used in ploughing matches. As most restorers, I have a number of war stories I can relate on a range of topics that may help other like minded and interested people. Perhaps my first p
