Default Hummer 125cc atv not starting

Hello everyone my hummer atv has spark but the sparks sparks very rapidly is that bad? Also i dont know if theres enough pressure from the engine, how could you increase it, and lastly the gas goes to the carburator but i dont know if its working, i have cleaned it and it might be broke, the gas button that goes to carburator needle presses more easily that before, so how do i exactly know if carburator isnt working. Please help thank you.

If it sparks, the ignition is probably OK. Rough check on compression is to press your thumb hard down on the plug hole, spin the engine over, if it blows your thumb off enough for air to escape, you have enough compression to start. If compression is low, check the valve clearances, you will find details of how to do this on U-Tube etc. If this doesn't restore compression, a rebuild is needed as the valves, cylinder head gasket, piston rings or cylinder is faulty. If compression is OK but the bike won't start, it may well need a carb clean.
