Losi 454 HELP

[austin]

I have broken in the engine and now when I start it up and I go and hit full throttle I eather stalls or boggs and it is pretty much flush with the end of the needle. Do u think I have a airl leak or something? I don't know

You say it is just freshly broken in, have you messed with the low end yet ? if not it may be a bit rich yet.....
also it is a balancing act between the low/high and idle.... beings as it is new, i would lean the low slightly and maybe raise the idle a touch and run it again......

I made a mestake of making the low end flush with the falve end and that was way to rich so I will give it a try today if the the sprinkling stops
