I have come accross a problem with a buggy motor that has me a little confused. After a few minutes of running the idle drops to a point where it will flame out on corners or pit stops, etc. If the idle is set correctly when the motor is hot it seems to run fine . After letting the motor cool down and restarting it idles really high.

The tune seems to be fine, and the motor doesn't overheat or do anything strange apart from this.

you may be alittle rich, on the bottom and what fuel are you using

What type of engine are you running?? Check your fuel line and pressure line, even make the pressure line longer. It may be air leak related not fuel related....

What kind of engine? What kind of carby? What temp is it running at?

ya i agree what type of engine????????
