FINALLY! Progress has been made!!!
After fighting a cold for the last few weeks, Sunday, dad and I were out messing with the Farmall H again.... Haven't been able to get this beast running right yet.
So, we decided to swap it over to 12 volt dist, instead of the mag. Put the carb back on, fired it up, and then discovered our first clue. The air mixture screw had ZERO effect on the running of the engine. All the way in or all the way out, it was over fueling, bad.
So, took the carb off (this will be the 7th time for those of us keeping track) and we did a quick air test, and sure enough, when that screw is ALL the way in, it is not stopping air flow at all!!
My dad was messing around with the carb while I was pretending to do something worth while, and I struck gold... I was looking at the actual screw it's self, and noticed something very odd. The first half of the screw was a different thread than the back half!!!
SOMEONE along the way, felt the need to replace that screw, however got a fine thread screw, instead of a coarse thread, and proceeded to "re-thread" the screw, by forcing it into the carb as far as they could!
So, I happened to have a spare screw laying around (brand new too!) and we just cut new threads on it, and put it into the carb. NOW it works properly!!!
Can't wait to get out there and try it!
However, the mother unit has promptly put an end to me doing anything today.... Still running a high fever, REALLY light headed and dizzy, and a whole list of other stuff.... yay...

In this segment we will finish up on our fasteners and then work with ways to keep them from loosening up in the field. Capscrews, bolts and nuts are not the only means of holding two parts together. When dealing with thinner metals like sheet tin, a long bolt and
