reason for injecting gas to cyls directly: gets around carb...carb may not be doing right...tractor isnt starting ...spark at plugs is yellow not blue,i dont know if yellow spark is ok for 6 volt farmall h ...my 8 cyl chevies and mopar will throw a lot more spark...seems to me that if i get 1 cubic centimeter of gas into the cyl i can get it to fire if carb is in fact the problem...
 
Get your ignition tuned up first. Yellow spark won't cut it. needs to be a blue-white spark that will jump at least 3/16 preferably 1/4 inch.
 
Think about what you said! if a put gas in the cylinder it will start? Fix what ever is not delivering the gas into the cylinder.

You need to hold your hand over the throat of the carburetor to see if there's good suction. Loose intake, worn rings, worn cylinder and valves leaking can all contribute to low manifold vacuum that won't suck that atomized fuel into the
engine. Make sure fuel is reaching the carburetor. Hal
