You are right. I did a search on google for a oil catch can and found a pic of one just like this one. What does it do and what are all the ports for?

Correct oil catch can. The hose thats on it, is the catch can vent. either one of the others go to the breather on the engine, with the rested blocked off like shown.

It looks like the red hose is ran to the breather on the motor it goes in right under the carb. the other 2 with hoses on them are just that cut off hoses and the one on the far right has nothing on it. there is a valve like a drain on the bottom of it. sorry for all the NOOB questions I just want everything hooked up right.

Okay then the red one goes to the engine breather and the open one is the vent, which should have a filter on it. Keep the other two blocked off. You use the drain after every heat/feature race and then add the appropriate amount of clean oil back in the engine.

No, its just a oil catch can, that collects oil dispersed during high rpm's of a racing engine. As the pulse jet carb designed for the Raptor racing engine has no provisions to vent the crankcase back thru the carb. thats why a catch can is used. It is also a safety feature to keep the oil that is expeled off the track surface and it keeps your kart/engine cleaner. They do make PCV kits for that engine.

The extra nipples are for venting the motor in more than one location. I vented mine from the valve spring cover and the side cover (PTO side) of the engine case. Depending on how the motor is mounted (angled) it will want a unique oil level. I believe B & S calls out about 15 ounces of oil to fill the motor. All of mine would push out oil, about the same volume everytime. Once I established how much was blowing out I subtracted that amount from the 15 ounce start point and I would get very little blow by in the catch tank.

Good luck and have fun with your kid.
