Thanks for the replies guys.
I am always scared that i will run it too lean and fry the engine so i dont like to run it lean.

to answer bubbas questions....
What is the engine,
OS .40 LA
How many turns out on the needle valve
2.5
is it spitting fuel out the exhaust
A little bit
Does it idle for a few seconds then slowly die
It does a little bit
Does it idle a few seconds then pick up a little rpms and die
sometimes
When taxiing around did you notice it start to burble and die or did it rev up a little and die
It wasnt very consistent, but it was about 40 outside so it could have been the temp, I dunno though....
