Massive amount of oil in the exhaust.

I have massive amount of oil coming out of the exhaust. I removed the oil jug thinking its dumping oil in the carb. How can I clean the stock muffler??

what exactly do you mean by comming out of the exhaust? is it leaking out as a black tar by the exhaust port on the cylinder? or is it comming out the silencer on the exhaust and is a black tar or is it still liquid normal color oil? if its unburnt oil its most likely the oil pump is adjusted too far open so it never closes or the cable could have bound up somewhere and its holding the oil pump open and letting it drain into your crankcase overnite then through the cylinder and into the exhaust. if its blackish and very sticky like tar you cylinder may be losing compression and not able to process the oil and fuel as well anymore and its building up in the exhaust and some of it is comming out the tail pipe as a sludge or tar instead of a well burnt smoke.

if you pulled the oil jug off make sure to premix the fuel or pour the right amount of oil into fuel tank when fueling or youll most likely fry your piston and rings. that being said if you do want to reuse the stock exhaust u can burn the pipe. look around on google or youtube if you want to see some other people play with a fire hazzard. its an old school way of cleaning 2 stroke pipes. but its dangerous and some pipes have fibreglass in the expansion chamber or they have a catalytic converter in there and it could melt. i would rather replace than put a bandaid on it cause sooner or later after burning the pipe its still gonna go bad. new pipe would be clean make much more power and make you alot happier in the end.

It covers my hand in oil and soaks the floor with oil.

If this is a stock pipe
It is a great reason to replace it ,After you sorted out how its getting so much oil.

For cleaning out the pipe you can just block one end prop it up and fill with gasoline or kerosene and let sit for at least a day.
some guys use brake cleaner or mineral spirits .
Just some kind of solvent to break down the carbon and oil.
Then pour out the gas and sludge .
Let it air out for at least a day Before firing it back up on your scoot.

If you have a radiator shop near you could have them dip the whole pipe in solvent for probably the price of a 12 pack of beer.

That's a good idea. I have a solvent tank at work. I'm guessing the oil pump put to much in the carb.

There is a ball/spring check valve to keep the the tank from gravity feeding oil to the carb,must be stuck open..Most are usually at the brass fitting at the carb...
