idling my engine

[sharkattack99]

What does it mean when after I drive my truck for a bit and then I let it sit there idling for a few minutes. And when I hit the throttle it dies? Kind of annoying just wondering it's a P3 picco .28 am I too rich still is my idle needle not set right is it the low speed needle that's to rich? Its perplexing.

No there is nothing wrong, Nitro engines load up with fuel when idled for long periods of time, and when ya give it gas it will die due to all the raw fuel built up in the crankcase. most will idle well for a few seconds and do it some will idle for a minute but this is normal for an engine running on nitro fuel.... one cure is to blip the throttle a bit to clear it out every few seconds.....

THe "Pinch test" is a quick way to tell if your LSN is close. Pinch the feedline off while it's running. If the motor races for 3-5 seconds then dies, it's good. Before that, it's lean, after that, it's rich.
