I have a couple of issues- after I got the tractor running the last time, she increseingly got harder and harder to start, until now, it will not start at all. I removed the carburetor (again) and seems that there are parts missing according to the IT manual I have. for example, the spring between the float and the needle valve, and the shut off solenoid. I also had replaced the points and condenser, which made it fire in the first place. I have readjusted the points, tried timing it, and had adjusted the valves during my last mechanic experience. After I had cleaned the carb and put in the new points, I adjusted the timing to what seemed to run very well by ear. but, i think was running rich.
Now if I try to start it, it floods. Also, let me explain the carb. It never had the shut off solenoid since I have had it - it ran well for a while, and I discovered the missing spring this time I pulled it apart. The screen is new into the carb. the gasket between the 2 halves has a rip in it, but did not seem to cause a leak. the gasket attaching it to the manifold is shot, and did leak when I tried to start it. There is strong suction when I hold my hand over the air inlet when trying to start.
To address the spark issue, I am not sure it is getting a strong spark either. If I pull a wire and ground it, while cranking, I get a spark that is yellow, sometimes blue - that will jump around 1/8 to 1/4 inch. The points, wires, condensor, cap, rotor, and coil are all new.
there is some play in the distributor shaft, but it seems the contact points are wide enough to handle some play.
Could this be an issue of:
Voltage regulator
stuck float / needle valve bad
too much play in distributor shaft
faulty coil
Or should I consider electronic ignition, or rebuilt carb.
I am stuck... and now that the school year has started, and I am in the middle of Marching Band season (teaching and judging) I have little time to play and want it running for the last couple of mowings and the eventual snow fall (even though a 4 inch snowfall cripples Delaware for days... LOL) I want to be ready.

Today's Featured Article - Search For Spares - by Anthony West (UK). Following on from the aquisition of the old Fordson F, I was very much in need of spares. As a novice though I didn't appreciate the fact that there were so many Fordson tractors made, that all the other makes seem rare by comparison. As far as I was aware a fordson was a fordson and it was only through trial an
