question fellas , does this sound right. i found that my car ( SHOCKWAVE) runs best when high end needle is 2 3/4 turns backed out and the low speed needle is just protruding the collar about 1.5 mm... it runs good here and i get about 10 minutes ona 75cc tank of 20% nitro. i would think its too rich. run any leaner and it seems to hesitate, not chug, when i get on it... any thoughts?
also does backing out the low speed needle richen or lean the engine out? i know im a noob so bear with.
clounter clockwise or out is richening it, leave it where it runs good bro, all engines are different, as long as its not running hot, your ok.
