Yep. I just looked it up. I thought maybe the decal would help identify the machine. Pretty sure it's a Carter Talon.

Hudathunk? Its similar. Not quite sure its a Carter tho...
If it doesn't match up with the original carb I would return it and get one that matches yours. That carb could be proprietary to a certain machine. I have 2 GY6 carb cores and neither one has that hole. If the original carb is still on the machine, try spaying a short blast of starting fluid in it then crank it. See if you get a sputter or pop from the ignition. Do a compression test too. Those engines eat piston rings and cylinders. They get hot and the cylinders wear. If you have weak compression you won't get enough vacuum to draw the mixture into the cylinder.
Any thoughts on what it might be?
I was on those sites too, that's where I came up with it being a 2004 model year. I got stuck after that. Good info. Let's hope he gets it running.
Without knowing exactly what machine you have it's difficult to say what everything is for or if you need those parts in question. The relay looks like the starter solenoid possibly, not sure about the resistor. Mopar used a ballast resistor in their older cars that had a high failure rate. It would reduce current to the coil and points when starting the engine to help prevent damage to the ignition system. This is the problem when buying unknown machines with no documentation. With so many Chinese buggy karts out there you need to know which one you have to properly fix it or diagnose it. I'm only familiar with the American Sportworks or Landmaster machines since there's documentation available and some support.
