Yep , Change the splugs to either 386 motorcrafts- C86 A/C's , next put a timing lite on it and being that it is a C263 and hoping that at some point someone before you did not upgrade her to the C291 conversion set the ing timing at 23 degrees BEFORE TDC. at full throttle . And ya need 93 octane gas , not 89 not 90 , 93 only . NOW HERE IS THE KICK we can no longer get straight 93 gas as now over here it is now laced with alkihol and it Does NOT work . Why not ya say well ALKIHOL is and oxygenating agent and it leans the burn and when ya lean the burn to keep the whacked out nut cases happy it makes this old mechanic vary unhappy . Why you ask well i have our 706 down at the moment with a torched out #1 piston from the last load of gas we got as our fuel supplier brought us a 250 gallon load of this NEW mandated 10% methanol blend 93 and never told us . We filled the 706 and hooked to the grinder and started grinding corn like we always do and she came under full load and before i could get to the PTO lever she started to loose power and you could hear the preignition , i got the PTo shut off and you could tell that she was hurt then all of a sudden she was hammeren hard due to the top ring getting up on top of the piston . So now i am not sure just what we are going to do . We can't get forged pistons that ya can afford to buy , ya can not get the gas that will work as i spent half a day on the phone with people tryen to get straight 93 gas and the best that we can get would be 90 octane as that is the best coming from the refinery thru the pipe line . 90 will run old 460-560's just fine IF they have not been up graded to the higher compression pistons . I know that back years ago the a lot of the guys around here that had 560 gassers had then upgraded with the 706 C263 pistons . BUT back then on farm gas was between 93- and 95 octane . The look on our fuel supplier's face when i dropped the piston on his desk was price less . As this is not the first piston that he has seen from us . Our 706 is the tractor of choice for feed grinding mowing hay raking hauling round bales planting or ya just need a tractor . It starts every time no matter the weather , no plug it in vary little warm up time . And besides we all just like it . But now i am not sure what we can do as i am running out of idea's . One fuel supplier said that he could get us what he called SPORTMANS gas and it is 94 octane BUT it only comes in 55 gallon drums and at the small price of 6.25 a gallon. Yea wright. Ba enough that the junk 93 is 4.19 a gallon and we use about 650-700 gallon a year on gas and 12-1400 in diesel . Myself i believe that we are fighting a battle that we can not win because nobody will stand together for two min and agree on just one thing and nobody will fight to try and get what they need . I do believe now that the days of the old trusted work horse are coming to a close as i am plum out of ideas and it is not from lack of trying . The EPA has beat us on this one .
