The last few times I've ran my buggy, I get ready to blast it with air when I started to notice grease type liquid when looking through the bottom of the chassis into the flywheel, it's only on the engine casing and I'm amazing it hasnt made itself into the clutch shoes. I guess the flywheel blocks any splatter from hitting the shoes. Anyways what could this be? Do I need to replace the main bearings? It's not much , but I'm being cautious cause I just broke it in last week.

One more thing, I pulled the car into the pits today to make a steering adjustment and struggled to get the car to fire, I traced the problem to the carb, where I could hear and see fuel boiling and bubbling, causing air to push the fuel back into the tank. On my fuel tank cap there is a swivel type thing where you plug in the exhaust line that had visible moisture, just a little bit. So I unplugged my pipe and blew through it to try and force fuel into the carb, there is a definate air leak in the section I meantioned. Could this be the cause of the hot fuel? Temps seem to be erradic, it'll run perfect with temps at around 220-230, then jump to 260-270 even when idling.
