The tractor vet said: (quoted from post at 09:46:48 07/18/10) You can GET BY on a 450 but ya ain't going to on a 460-806 and yes i am that good a mechanic. and i do not have 55 years but 50 years of wrenchen and a lot of race engine building under my belt . And like i said READ the org. Operator manual for fuel requirements. And LEARN about the modern fuels. Gas started to change in 74 and octane levels started to drop Gas powered tractors went out of production . And if ya never saw a piston melt then you have not been around many engines that WORK. And if you are not open enough to try something that i have been over and over for years then your one of them know it alls . As for me i am still learning . And we around here still run I H gassers each and everyday and if spending a little extra to keep them going then that is what we do . Plus the fact that when these engines were new fro THE factory they HAD forged pistons in them and not we get cast pistons to rebuild them with and even in your 450 you do not have a cast piston anymore. and the cast piston will not handle heat like a Forged one will . as to the ing. timing i know how to set timing and i am one of the OLD FARTS that can STILL us a dist strobe to check and redo a timing curve as i wish i had a five dollar bill for all the dist. that over the years that i have worked on to rebuilt to factory spec. or tweak then for racing . The hours that was spent building and dyno testing engines for racing and Gee for some reason the ones i built for some reason seemed to do well . And the engines that i have put together for the few good friends to go play tractor pulling with for some reason have all been winners . But ya know i have been on here for how many years now HELPING people with there problems FOR FREE and sharing my knowledge FRO FREE then we get people like you that try and tell people that well you don't need that then YOU go and try and make it work for them . I made a decent living fixen tractors for a long time for people And like i keep telling people the gas of today is NOT the gas when the tractors were built new. So if you doubt my work the try and run ANY car, truck or tractor made back then and make it run and do what you expect it to to on the gas of today . Case in point try and make a say 68 Ford galaxy with lest say a 390 2bbl Reg fuel run on the what we call reg fuel today and see what happens or oh what about the same car with the 390 Prem fuel 2 bbl or what about a 65 mustang with a 289 4bbl . Oh wait why did ya have to run prem fuel in a 391 HD ford truck motor or what about the 534or 549's or the old 57 Macks with the 6 cylinder Thermodines??? . and have you ever had a lab test the gas to see how it burns and how EXTRA HOT it burns today . No i don't figure that you would pay the money out to find out as to WHY pistons melt or swell .025-.026 above the top ring and guild to the sleeves . Why does a 225 slant six Chrysler engine in a Massey 300 run 20-40 degrees hotter on 87 then it does on 93 ???? when everything is set where it is suppose to be ???? . what i am good at i am vary good at . I know my older Mo pars and my older Ford and i know my I H tractors up to the 88 series . yes it costs us 40 more for 200 gallon of 93 over the 87 BUT we do not have problems when running the Min. fuel requirements for that tractor . IF we could get 95 then we would be running that and i could PUSH the engine a bit more But i feel that getting a good 87 horse out of a C291 is good enough we will leave it at that.

Today's Featured Article - The Cletrac General GG and the BF Avery A - A Bit of History - by Mike Ballash. This article is a summary of what I have gathered up from various sources on the Gletrac General GG and the B. F. Avery model A tractors. I am quite sure that most of it is accurate. The General GG was made by the Cleveland Tractor Company (Cletrac) of Cleveland, Ohio. Originally the company was called the Cleveland Motor Plow Company which began in 1912, then the Cleveland Tractor Company (1917) and finally Cletrac.
