I have reviewed the manual and I don't think I see a specific situation like mine listed in the troubleshooting. My problem is that about a year after I got the mower, the battery started losing power and I had to jump start the machine. It would start periodically, but there was always a problem keeping the battery charged. I got a new battery and it was ok for a while, but then the electrical problem started showing up as just hard to start - no consistent spark I think - and the engine would flood while I was trying to get it started. I took it to the local Toro shop and told them there was an electrical problem, but they just did a generic clean up and tune up without ever telling me there was anything specific wrong. It started once, and then went back to its old behavior. I was able to jump it one time, and it ran for about 30 seconds after I disconnected the jumper cables, and then it slowly died. I have not been able to even jump start it again since. I replaced the plug, which was in fact a new one anyway, and that did nothing. The battery won't even muster enough juice to crank it, but it will crank if I hook up the jumper cables. Just no spark to burn the fuel. I'm not sure what to replace.

I reread you entire post and I don't think it is an engine problem, but a tractor problem. If you jumped it and it ran until you disconnected the jumpers, that is an indication that tlhe battery is bad. A bad battery will suck all the available juice from your jumper battery. Try disconnecting the unit battery and try jumping directly to the + & - leads. It should start.
