if the oil is coming from the 1/2" breather pipe connected between rocker cover and air cleaner, then you got blowby. Either rings are worn or valve stem seals are shot. Most old gems get it when revved, aqnd if its really bad you may even pop the dipstick...

the ONLY for oil to get to the carby, is thru the rocker cover breather, start the engine with the oil filler cap off, if there a heap of air pushin out it, then cylender preassure is blowing past the rings it probly shoots a puff of smoke out the exhaust when decellerating from high revs, yes? if heaps of oil is pushin out then time for another engine swap!

is the oil in the air cleaner???? or blown onto the outside??? and all over the carb??? if the oil is outside the carb... maybe the tappet cover gasket moved.. and is pumping oil out onto carb/maifold/aircleaner..
Its not a hard thing to overlook!
If its a new motor.. then its possible the rings were broken when assembling the motor, this is one cause of it... the other is the rings being frozen into the pistomns and not expanding as they should, causoing blow-by
even tho the motor still runs fine!

like Extra gem said, the only way oil can enter that area is by the pipe from the rocker cover, there is no way gaskets can make oil enter your air filter assembly, is the oil only there after alot of full throttle reving? if its there after normal driving you got REAL bad blow-by...
