oil injection pumps are known for failing and when u run without oil you fry your bearing and topend. much safer to mix it yourself so you know its getting oil. 32:1 recomended and i use klotz 2 stroke oil and it smells shweet!
same thing with outboard motors. get a few years on them and every one gets scared of the oil injection. mix your own is a you never have to worry if its working or not.
i didnt block brians off, just took the gear off,
pulled the houses off, and put a piece of black gorilla tape
over the hole in the cover, and mix our own,
blendzall, smells schweeter then klotz
