Order some. Not too late. I run tubes in all mine. Not all front tires, but any rears that I've had apart.

Good Information in the tech section. Thanks for the heads up on that. Also, I believe you are right Gompers. I looked this morning and I believe my voltage regulator is fried. I checked the wiring harness going to it and the S/G and everything is good. Big shout out to Mikescubcadets.com. I bought a harness and a points wire and it looks professional. If you have not gotten a new harness for an old cub, do it. It looks amazing and the diagram makes it so easy that even I could hook it up. It was a bit of a pain to feed the harness through an already assembled tractor, but it wasn't impossible. Anyway, I am going to get a new regulator, a hot battery, and then we will see what is wrong next. I am assuming I will have to polarize the system with a new regulator. Correct?

Well tomorrow is payday, so why not

Glad you chimed in on the thread. I asked this just now in a post above, but I am assuming that I will need to polarize the system with a new regulator. Correct? I read in the link above that I will need to jump a wire from the Batt input to the Gen input on the voltage regulator.

Will do. Thanks for the advice guys...

They say you should. I don’t think it’s necessary, though. It won’t hurt anything to do it as long as you don’t shove too many amps into it for too long and fry a coil wire in there.

Also there is a difference in the terminal configuration between the new Chinese ones and the original ones that are on there. The Chineseium ones seem to work fine, but make sure you have the right wires on the right terminals.

And you’ll need a new battery for it anyway, so make sure you do that too.

Glad you’ve got it running!

No, you do not need to polarize a starter/generator system. Only a generator system. And it's not the regulator that gets polarized in the process...it's the generator.

Thanks for the feedack.

It's funny you mention the Chinese VRs. I just got through looking at them and looked on OCC to see if anyone had advice. Apparently lot's of folks have discussed this. I do see that the 4 Terminal ones include a Load terminal. Apparently I need to NOT use this and insulate it. I've looked into the one I plan to buy and believe there should be no issue in wiring it up. We will see though.

I know that I am rolling the dice on these Chinese options. apparently there are a high rate of failures.

Just about anything the Chinese makes has a high failure rate! I have the starter/generators rebuilt and buy American made voltage regulators.

Yeah you don't need the load terminal. I just put some heat shrink tubing on the one I did so it didn't contact anything, since it's hot. If you wanted to run your (non-LED) lights or electric lift off of it, that what it's there for. Otherwise, just ignore it.

Alright guys. I still have a couple of bugs to work out. The first is pretty simple. I just need to adjust my carb so it idles little lower. It's running a little rich on fuel, but I'll tinker with it over the next day or so and get it right. The second one is getting the best of me... I have adjusted the nut in the picture below at the end of the red arrow all up and down the threaded rod and can't seem to keep the shaft from spinning when I press the clutch. I have tightened it all the way day, loosened it all the way, and everywhere in between and when I press the clutch in, the SOB is still turning so I can't put it in gear. Any thoughts? I have read in my manual that I am supposed to have a gap of 0.05", but I can't determine where that gap needs to be. PLEASE HELP! I would like to put this girl in gear and take her for a spin.
