How much fuel is too much to be exiting the exhaust?

Hey Guys,

Obviously I am a noob at nitro buggies and cars I keep reading about running in and tuning and was just wondering after the running in or break in period, should fuel still be exiting the exhaust? and if so should it be alot of fuel or a little. In other words if you hold your hand just away from the exhaust should your hand end up quite well covered in fuel after say 30 seconds or so. Hope this makes sense.

if your hand is covered in bout 30 seconds its WAY too rich...lean it out...if your done with the break in just listen to the motor at idle, bout half throttle, and full speed...she'll tell you what she wants, whether it be more or less fuel...gurgling or hesitiation means its too rich. screaming or popping can mean its too lean...but to answer your main question, you should have a very very light mist of oil coming out, but not very much either
