My luck

Postby Csmith » Tue Mar 08, 2016 8:38 pm

So, I spent the weekend on my new to me 49 cub riding around getting old rings re-seated,gaskets swollen back up,etc etc. I had changed all of the fluids and done all of the things you are supposed to do to bring everything back to life. and went about life as normal on my little farm. I was just finishing up turning the second acre when i heard a knock (thought it was a rod knocking). I stopped the tractor immediately, and diagnosed the problem as the fan pulley. Ordered a new one, and continued on with my trusty 68 Powerking, pulling my 23a harrow. I got notice today that my parts where on there way and decided to risk driving the Cub back up to the shop. 10 foot from the shop, needs a new radiator too :(

Yup. Fan bearings gave out on my Cub, fan took out the radiator.

That is a rough way to start with a great little tractor.
Sorry for your loss there.
Probably one of the first things that should be serviced is that fan hub.

Yea, I just found out the pulleys on the replacement fan assembly don't line up with my gen either. I had hoped to keep her as original as possible, she might have to wind up with a 12 volt genny yet.

OK, new radiator is installed and with a little redneck ingenuity the belts are lined up and she is back to running again. I am still having a problem with the float in the carb and the fact that my choke keeps easing back on and flooding the engine. Was there a spring to keep it in the off position or????

The choke rod has a bend in it, behind the dash, to hold the choke rod in place.

If the choke rod is holding in the dash, there is a clamp on the back side of the carburetor that the choke rod attaches to. Perhaps the clamp is loose on the carburetor choke shaft.

Hi,
There is a small spring in the carburetor to keep the choke in the fully open position, and to make friction when the choke is partly or fully closed. It is rather flat looking, not a regular looking spring. Here is a page from the Cub parts book showing the IH carburetor, the spring is number 15 in the pic.
If the choke lever at the carb moves with no friction, the spring is either bent, weak, or not there. Or the end on the choke shaft that rubs on the spring could be damaged.
I think you have to take the choke shaft out of the carb to replace the spring. Click on the pic makes it bigger. :)

The arm on the choke shaft that the rod fits into is adjustable. Make sure it is positioned at six o'clock with the choke open so the weight of the rod is not causing it to rotate. The shaft should be knurled so you may have to loosen the arm, slide it off a little, rotate, slide back into position, and retighten.
