The MAIN REASON FOR GOING TO A LITTEL HIGER GRADE OF GAS IS THAT IT burns longer and does not leave that mess as bad . When i tell somebody something it is because i have already been there and done that . I had a custermor that had a 400 Farmall that i myself did the carb because it was fouling plus faster then you could put them in and this engine was fresh and the rings were seated . They used this tractor on a mixer wagon twice a day i started working on this mans tractors and combine after he got mad at the one other guy that use to fix tractors in this area and after many hours of working on this one 400 tryen to figure out just why it did this and everytime we would look at the plugs it was fuel foul just for Shutts and giggels we drained the tank and took two five gallon cans down to the littel gas station at the end of the road came back to the shop and put the ten gallon into this 400 with a new set of plugs and ran it on the dyno at rated power for and hour and sent it back , i told the farmer to go down to the gasstation and get the 89 for it and not use the gas that he had in the tank for two weeks , well for two weeks that 400 ran fine for two weeks on the 89 the day that he went back to the 87 out of his tank he was back at the shop complainen that it fouled the plugs went back to the 89 and it was fine and when pulling the plugs after a month they were still looken good no sooting . Now let see here i still service four Super Mta's one 400 gaseer one 460 gasser two 706 gassers two H's a hand full of gasser deeres and all of them are working tractors as around here we farm with what most people play with . Now all of these tractors are either running the 89 or the 93 octain fuel and fuel has changed a bunch since these old tractors were built new . They do not have fuel injection or a hot ing. system they do not run high RPM's and they do not run as hot under load as does a car or pickup engine does . Now if ya could or wanted to install a MSD 6 box on it with a super hot MSD coil and gap the plugs at .045-.060 then that may work well as the spark from one of those systems will knock your socks off not just a tickel like a stock system does.
