    F12 Fuel Pump Breather

    These tractors spent their entire useful life working fields in dusty conditions. They had lots of oil contamination/wear issues and had numerous production changes to try to alleviate the problems. It is doubtful that it will see anything close to those conditions in the next 80 years

    I-12 IS-1507 starting procedure and spark advance

    There's no point, I am the one who understands how this works. It's worked exactly the same on every mag with a spark lever up until the process was mechanized like in a Fairbanks Morse FJ. Sometimes you just have to accept things you cannot understand.

    I-12 IS-1507 starting procedure and spark advance

    I can explain it to you, but I cant understand it for you. Here are very simple facts, the impulses ONLY function is to charge the coil. The points Only function is to fire the spark. Neither of them can perform the others function.

    I-12 IS-1507 starting procedure and spark advance

    okay here we go. we're going to use piston #1 to try to explain this. insert crank and turn.#1 goes down pulls in a charge. #1 begins upward compression stroke, Rotor is approaching #1 terminal, Impulse dog engages non adjustable catch, MAG internals STOP rotating holding their position...

    I-12 IS-1507 starting procedure and spark advance

    Well thats because it doesn't. It simply rotates the points to a different position which changes the timing and it has absolutely nothing to do with the impulse. The impulse is timed for starting only as it disengages as soon as the engine fires up, there is absolutely no reason for the spark...

    1936 I12 gas in oil

    lets see if this vid of my F12 works. the fuel pump line goes to the tee then one side of the tee goes to the carb and the other back into the tank, It's not a standard tee as it has a restriction in it ensure flow to the carb when it needs it.

    1936 I12 gas in oil

    Ron is correct, no way that carb could hold back an electric fuel pump without a reflow tee to return excess fuel back to the tank.

    Kenny Kizzle F-12 carb question

    The only direct replacement will be from a donor carb, you can modify one from an H carb but it will need fitted and the lower side hole drilled with precision.

    Row Crop Tractor

    Well, the Farmall was in fact adjustable tread, Starting with a standard tread or a narrow tread, they used inset and offset wheel equipment which together allowed for an unbelievable range of tread widths. Easily changeable? absolutely not, but the Farmall started the row crop revolution and...

    Row Crop Tractor

    The Farmall was the first rowcrop. It allowed the farmer to do all the work necessary with one tractor. Tillage, Planting, Cultivation, and Harvest. Previous tractors could till and plant but row crop cultivation was not possible due to low ground clearance. Cultivation was the key to the row...
