Do you use castor for the smell?Cause its dirty oil.Use an oil as you mentioned,like mx2t ,yamalube,or golden spectro if you like the smell of some what castor.Try running these jetting specs @32:1 mix.

168 main
55 pilot
stock needle @ 2nd from top
air screw @ 2 turns out

Try it out and see if it work,tune from their.
