I have never said 97 octane but it would be nice . What i did say is the Minimum FUEL REQUIREMENT FOR THE LATER 4cylinder and 6 cylinder engines is 93 . Now i am by no means a math major or thermo engineer , But i can read a plug and for the past fifty years built engines carbs and i can defiantly do a dist. i am not a computer wiz and i do not have a scanner if i did i would did out the lab report on the gas we had tested years back . As long as we run the 93 LIKE the owners manual says we have no problems . Yes the compression ratio is up on both 706's due to block decking to true the deck and there was about .007 taken off the deck on one and nine on the other one head took .009 to clean up and one took .012 . NOW the question is was it milled before and how much or are we the first to clean it up ?? If the timing correct yes as both dist. have been run on my machine and one needed a new set of springs and the other needed a new plate. Both run out as per the book stated. is the ing. timing set yes 18 degrees at wide open throttle . Each and everything has been gone over and each and every time they go down it is from someone putting in 87 either the fuel supplier sending out the wrong stuff or the last time My buddys son went to get gas and not thinking got 20 gallon of 87 while mowing away from the main farm as the gas station was a mile away and the farm was eight. I am just stating what the Chemist told us on how the 87 burns verses the 93 that we get today as what they call high test he told us that the 87 is a hot flash burn and that the HIGH test (93) is a cooler longer burn that will give more power from the longer burn.

Today's Featured Article - Women and Tractors - Tractor Engine Repair - by Teri Burkholder. One of the great things about working on a tractor engine with your other half is that you know what he is thinking of at all times and can anticipate his every move and his next thought of what he will do. With Ben, anyway, I can tell! He'll be busy working and I’m handing him tools and he says, "give me that..." and I’ve already got it in his hand or "hand me that....."and I’ve got the portable light right where he needed it placed to see. "Run in the house and get me a...."as I open th
