engine problems

[Ant]

I've just recently bought a nitro rc buggy, I'm just in the run in process and have done 6 tanks of fuel, when I come to start my rc it starts first time but it seems sluggish and wont accelerate properly. I was wondering if any1 had any advice. Cheers

Are your needles set to factory settings and have you changed any from factory settings?

It needs to be tuned during the break in. Now that you've done it the LSN is much too rich for it too run well. You need to lean the LSN a little bit at a time while you run it, and once you get a good idle and a good launch you start to adjust the HSN for wide open throttle.
