Sounds to me like your engine is way off. The low and high end adjustments, although separate work together and everytime you adjust one of them, you should readjust the other until you bring it all together. Check you idle by piching off or removing the fuel line from the carb.

If the rpms increases before the engine quits your low end is to rich. If the rpm just goes down and dies-too lean and adjust as necessary.

Also chek you fuel lines for crimping. If they come out of the firewall and make a sharp 90degree turn to the carb,could be crimped enough to cause a lean run , overheating and landing with your throttle stick full open yet barely running and hottttt.
