Dear All,

I would need some help,today Ive flown my .46la & later after it went dead stick,Landed it.I let it cool down & then tried to re -start but there was very little compression,therefore pack up & went home,At home again tried but no result,after dis-mounting the engine,checked for leakage-back plate,glow plug,carb all ok,filled fuel & pumped in air but no leak,Before all this I had slightly opened the carb 1/2 turn to run engine cooler & tried starting engine,again i returned the carb needle to it original place but still compression.

What could have gone wrong?
Engine is almost 2 year.
