Can anyone help me identify this buggy and engine?

I have the chance to buy both for a combined price tag of $400. Seems like a great deal to me. The buggy apparently runs fine with the Mitsubishi engine, but they're willing to throw in the Kohler for free - so why not, right? The Kohler runs without any issues as well. Would it be too much for this buggy though? Thanks!

Also, any thoughts on what kind of torque converter I would need for the Kohler? Although I don't know the exact model, being that it appears to be a v-twin, I am wondering if a 40 series would be enough.

Its just some generic china buggy most likley came under several different names. and honestly a predator 212 is more than enough for that. But id get the biggest converter that fits your shaft diameter if your gonna try and use that motor.

Thanks, BeefKing69. Turns out that it is a Tomberlin Firefox 620. I bought the buggy and sold both the Kohler and the 6 HP Mitsubishi engine that was on it. When all was said and done I ended up making $50. Also, I did decide to go with a Predator 212 with the following mods: Mikuni VM22 with a K&N filter, custom exhaust and 18 lb. valve springs. Currently it has an 8 tooth clutch and 70 tooth axle sprocket. Problem is, the axle sprocket is so big that it doesn't leave a lot of clearance. I plan to switch the axle sprocket to a 60 tooth, which will leave me with a 7.5:1 ratio and more clearance. It could climb okay before, so hopefully the added HP will keep it that way despite the ratio change.

Your welcome thats cool that its a tomberlin....didnt know they even made gokarts like that...thought they just made the crossfire 150s and how much are performance parts for the predators?

Edit....You might look into a comet converter for the 212.....would be a lot better than the centrifugal clutch setup.

Yeah, I guess they used to sell this kart at Costco. I'm kind of surprised there isn't more out there on them. It seems like they could be fun little karts with the right upgrades.

Although I've also decided to get all new tires put on, because I've actually made money so far, in the end I will spend about $350 on it. Not bad for a little kart that will be pushing around 10 horses.

Also, the kart already had a Comet 30 series on it. I might be pushing the limits at around 10 HP, but I'll give it a try first. If I end up blowing up the clutch I'll grab a 40 series with a 3/4" bore.

Are there by chance any experts on jetting Mikuni carbs out there? I am just having a hard time finding anything in my online searching that is helpful. Thanks in advance!

No idea on the predators but there is a big aftermarket following for these motors so there shoul be some dedicated forums on building and tuning them.
