APOLLO 125CC LOSING COMPRESSION AFTER TRYING TO KICK START IT

hi guys,
i got an apollo 125cc which is brand new but was sitting for some time. first day i got it on and it shut off and didn't turn on again. i would kick start it, it would rev super high then shut off and would lose the compression for a little then same thing again. I then got a new Mikuni carb online and replaced it and now the bike wont start and the same thing is happening, i try to kick start it and it sounds like it wants to start but then loses compression again for a little bit. Please help.
