Case 446 won't stay running

OK, this is one of those fuzzy questions that may be too general for an answer, but here it goes:
446 was running fine if a little hard o fuel. Occasional back-fire when shut down if not idled for a short time with low throttle. So, the throttle cable broke at the control head. Since it looked like I would need to remove the hydraulic tank and plumbing to even get to it, and given the growing season, I elected to make a quick bracket and mount a new control head and cable externally. Now, the mower will start but dies almost immediately. No difference if the choke is open, closed, or half way. Same with the throttle being full open, closed, or half way. It does have a full tank of fuel. I can't imagine what changed given that all that was done was remove/replace the battery, and install the new cable. I did verify that the cable actuation direction is as original.

Not much to work with but any suggestions?
 
I'm not familiar with a Case 446. What engine is on it?

When you say it will start but quit, it sounds like you aren't getting gas. At least not enough gasoline flow to run. And the problem whatever it is may be totally unrelated to your throttle cable problem.

Is there any chance that you stood this tractor on end or laid it on it's side while you were doing the throttle cable repair? (I know. But it has been done before.) I'm just wondering if trash moved around in the tank or carburetor.
 
Dp you have a jumper wire consisting of a length of 16 gauge wire with an alligator clip on either end? If so, then clip one end to the POSitive battery terminal and the other to the POSitive terminal of the coil. Then use the key to spin the engine over and see if it stays running. If it does, then it would seem that you have somehow interrupted the lead coming from the ignition switch to the coil. You did mention that you removed the battery and the ignition switch is located behind the battery. Over the years, plenty of voodoo often takes place with the wiring. Past owners cut wires, use Marrettes to make connections or just twist wires together. You have to start somewhere so a close inspection of the wiring is a good place to start.
