I bought mine from tower hobbies two weeks ago.It has the remote needle valve,and the booklet that came with it says 4 to 5 turns out for break in setting.So i was scared when i brought that needle down to 2 and 3 quarters,but it ran alot better and the motor actually got warm insted of staying room temp after one tank at full tthrottle.
So it seems like you guys are right.I got puddles of caster oil all over from it spittin.Just that manual is freakin me out with its 4 to 5 turns out.
