Ok, I have a Sabre lawn tractor with the 18hp intek vtwin. I was mowing the lawn one day and all of a sudden it quit running. I thought I ran out of gas, but no.
Now, I have been starting my lawn mower by bi-passing the starter switch. My positive battery cable at the battery is corroded and wont get a good connection. I haven't got around to replacing it. So I would just jump the starter with a jumper cable from the positive terminal to the starter.
now that we got that out of the way. The tractor was not out of gas. I checked the oil, and it was a bit low. I put oil in it. Wentto jump start it, it cranked over but would not fire, but immediately smoke came pouring from the front of the engine. Smelt like electrical. Sure enough, a ground wire fried on the front of the engine. I have no clue what it is. Fuel shut off switch? It's on the bottom of the carb. I sprayed carb cleaner in the air cleaner to see if it would fire up. It fired up immediately with more electrical smoke, I heard a bad knock during the 2 seconds it was running. I also noticed some oil leaking from the left side of the engine.I have had nothing but problems with this sabre, but never the briggs engine. It looks terminal, but who knows, maybe it's an easy fix? help is appreciated! Thanks

Your description of the condition of your tractor and the "Saturday night mechanics work" says that proper repairs aren't being done. You can't neglect equipment and then expect it to work perfectly. You may have already gone beyond what can reasonably be repaired and will need to put some serious cash into this to get it back up and running properly. D-Dogg has advised you correctly on getting the manuals and diagrams and understanding your tractor (we all have to learn this!). The service manual for a tractor is a worthwhile "investment" not an expense! Check all the wires before you cause a fire and destroy the tractor.
