The carburettor sits on top of the manifold with an insulating washer. If the engine is hot some heat will reach the carburettor after stopping the engine, the insulating washer is not perfect, and will vaporize the fuel. Even the gasoline engines had a heat control flap in the manifold that can be adjusted to vary the amount of heating the fuel-air mixture gets before reaching the cylinders. There were two fuel arrangments, the ones on the F-12 and some early F-14s where both fuels fed the fuel pump, the fuel from the pump went to a small vertical chamber sticking up through the hood just in front of the tank, this had a vent to air at the top, a pipe to the craburettor and a return back to the pump inlet line (this provided some head to the carburettor). The other version used on the later F-14 and all the W-12, O-12 etc. tractors had only the main fuel going to the pump and in this case the line from the pump went to T junction in front of the top of the tank, the wee upstand inside the tank gave about 1/2" head to the T, the other side of the T went to the carburettor. If it was a kerosene or distillate engine the gasoline starting tank was, in this case, set in the hood (a 7/8 gallon cylinder on its side) with two valves giving feed from the pump for normal running or feed by gravity from the gasoline starting tank for starting. If you do not have a starting tank it takes a bit of cranking to get the carburettor full if it has emptied by evaporation. There is also a fuel filter built into the inlet to the carburettor and if this is blocked then you could crank for ever!

Today's Featured Article - Earthmaster Project Progress Just a little update on my Earthmaster......it's back from the dead! I pulled the head, and soaked the stuck valves with mystery oil overnight, re-installed the head, and bingo, the compression returned. But alas, my carb foiled me again, it would fire a second then flood out. After numerous dead ends for a replacement carb, I went to work fixing mine.I soldered new floats on the float arm, they came from an old motorcycle carb, replaced the packing on the throttle shaft with o-rings, cut new ga
