Any idea what kind of gokart this is?

I'm not too sure, but it is a sweet kart. To me it looks like it has a Dingo stance, but I don't think it is one

It is definately a Carter Bros judging by the jackshaft setup and the warning tag on the front axle. Not sure if it is the old style talon or a superwheels.
Looks like his is http://www.gopowersports.com/carterpdf/1435.pdf this cart. Not sure if mine is a separate model or not because a quick GIS showed carts with the same wheels and tires as mine which suggests it is probably "factory" like that.
18x9.5-8... The closest I can find from this site: http://www.gopowersports.com/carterbrothersgokarts.aspx is the model 1755 (http://www.gopowersports.com/carterpdf/1755.pdf) BUT my cart has a straight front spindle support bar.
Anyways, I am glad I found out a little about my cart today. It understeers like crazy though with the big tires on the back. Not sure if maybe the steering is off and that is causing it or maybe contributing, but the big tires on the back with skinnies up front doesn't make it a handling queen for sure.

I noticed your splindles are slightly different to MKII420's, but they both have the same problem; no Ackermann! Addressing this issue will probably solve your steering issue
Now I know what ackerman is in theory, but I am far from an engineer and every time I try to learn more about it, it swooshes over my head. I know it regards the angle of the wheels themselves in a turn to compensate for one tire spinning fast than the other. I think mine does incorporate ackerman angle, but it is not obvious without seeing it in action. Let me gran a camera and post a pic. In the mean time feel free to use laymans terms to explain ackerman angle to me lol

How to check for Ackermann:
Tie a length of thin rope or string to the centre of your rear axle.
Stretch the rope to the front so that it passes directly under the pivot point of your front spindle.
When the steering is straight, the pivot at the end of the tie rod should be on the same line.
Looking at your spindles, the steering arm appear to be at 90* to the axle; this won't give you Ackermann

If you look at your second pic, you can see (without even getting out a protractor) that the left wheel is turned at a greater angle than that of the right wheel; You need the reverse effect; the inside wheel should turn in more than the outside wheel.
There are three angle to consider when looking at steering: caster, camber & toe.
Camber is the horizontal angle as viewed from the front of the wheel (as seen in pic 4.
Caster is the horizontal angle as seen from the side of the wheel.
Toe is the angle of the wheels as viewed from above
The camber on your wheels looks a bit excessive but i wouldn't worry about it.
Try the Ackermann test I mentioned & get back with the results. Include pics if you can

Does this help?

Actually yeah that is incredibly helpful haha. So the tie rod should connect to the spindle on the same plane as the spindle connects to the frame and the center of the rear axle. I wonder if there is aftermarket spindles that could correct this issue.

Do you have a welder? If so, if you cut a V in the right place you can modify them yourself.
Note: Don't cut all the way through, leave a little over 1/8", that way you won't need three hands to put it back together.
Start at 90* & slowly work your way out until you get the desired angle (cut, bend, cut, bend, etc).

To correct the Ackerman, can you cut the steering arm and re-weld it at a correct angle?
BTW, I just bought a carter "Hot Bodies" kart, but it has dual rear brakes.

Darn. Do you know anyone who does? A shop would probably do it for a few dollars.
Maybe, not sure. Most true Ackermann spindles have rear facing arms but there may be some forward facing ones available. However, matching the angle will be your biggest problem. Done this way, it's custom fitted to your kart so, you know it will work.
Wouldn't a rear facing left spindle become a front facing right spindle and still be on the same angular plane with the center of the back axle? I never took anything beyond algebra in high school and even that was years ago so I am a bit under educated.
