Coolster Kodiak Electrical issue?

[Adub94]

Hello all! I have a Coolster Kodiak I bought for my boys and I'm having a little issue with that I cannot figure out.

I've replaced the battery, coil, plug and solenoid. But the machine is still having issues. All I can do is spray starting fluid in the carb to get it to turn over. When the machine turns over and starts, it's followed by 3-4 pops while on the throttle and it stalls out again. After the pops there is a slight electrical smell as well.

I really want to get this thing going for my son so any help on what part I may need or a simple fix is greatly appreciated!

Thank you!
