Tobo is correct in his question. Did you disconnect the points?

Point cover is pretty important. Apparently, you've not yet had a wet blade of grass (or other object) land on them.......

Besides, the fact they need to be protected, they need to be kept dry and free from corrosion and the oil that tends to leak out the valve cover.

Yes, I tested once with the points connected and open, and another time with the points disconnected. The results were the same 0 volts. i should have the ignition coil today, so weather permitting i should be able to replace it today. Now I did a quick search for the points cover on google and I got a lot of results for stuff on eBay. Is there a part number for the points cover, and is there a better place to buy it from rather than eBay? You guys have all been really helpful and I'm very appreciative for the help, thanks.

Alright guys I got the new ignition coil, and now I've got healthy spark at the points and spark plug! I static timed the engine as directed in the technical section. Unfortunately it seems like my battery is too weak to start the tractor so I've got it charging now. Will update again once I try to start it with a charged battery. It was a bit too dark for photos today, but I'll try to take some tomorrow.

There should not be a healthy spark at the points (I'm assuming when the points break). If there is then the condenser isn't doing it's job.

I hooked up the battery today, took out the spark plug and turned over the engine a few times since I had flooded it, changed the oil, and it started right up! I I adjusted the high speed needle on the carb and it ran like a champ, I did have some issues idling the engine less than half throttle, it would start to die off. Anyway I'm gonna work on that tomorrow. Also I notice the exhaust was RED HOT on the inside while running at full throttle. It died off after about 20-30 minutes of running at full throttle, I couldn't it get it started back up after that. I'm going to decarbonize the engine and replace the head gasket in the next few weeks. I took pics of the tractor finally and the hot exhaust. I'm going to post that later tonight. Why do you guys think the engine would just slowly die off while at full throttle after running for 20-30 minutes?

sticking valve, bad coil just to name a few. when it died did it still have spark?

Thanks Terry, I'm going to decarbonize and replace the head gasket within the next few weeks. I'm guessing that also accounts for the engine bogging down once I put the hydro out of neutral? Here's a photo of the red hot exhaust. Once again, thanks for the help everyone.

That doesn't look good, I've never seen one get that hot. It's either running lean or theres a mouse nest in the blower housing keeping it from cooling or both. It could also be some carbon build up on the head that's raising the compression, its probably a combination of problems causing it.

That's a pretty hot exaust there. I'm not going to speculate beyond the sticking exaust valve that I mentioned earlier. An expert will tell you for sure but when I have one that dies when it gets hot that is what it usually is.
