I'd suggest you start by asking the seller what brand/weight of oil is in your engine now. Some of the specialty kart racing oils brands have additives that dont mix well with other brands. Even after you drain the old oil, some of the residue will remain and this can sometimes cause problems when switching to other brands.
If he'd just previously used oil made for cars, (synthetic or petroleum based) there probably wouldnt be any problem switching to most any other brand of automotive oil. But if he used one of the special kart racing brands, you'd want to either stay with that same brand, or flush your engine out with mineral spirits before changing to another brand.
Guys that race engines like yours (w/15-degree motormounts) typically used 14 ounces of oil. You'll just need to use a measuring cup to get the right amount. (You could use 16-ounces if you want, but it'll probably puke those extra 2 ounces out your breather at high rpm)
I use/recommend strait 30 weight Redline brand, synthetic racing oil in my racekart engine. I buy it from a local automotive speed shop, but you could find it online too.
Are you running gasoline or Methanol in your engine?

I've been trying to help you figure out what brand your kart is, I've posted your pics on a kart racers forum. We're still not sure what it is, but you can check out the thread here:
