you have low compresion due to a scored pistion or barrel. Not enough to stop it firing, but enough for it to lose compression once the engine has started to heat up due to metal expansion.
Effectively it's a write off.

Hi. Can try this . There is a fuel filter inside your fuel tank use a wire hook to lift it out. Remove filter from hose clean excess fuel from it then try blowing through it there should be no restriction in doing this. If there is replace it.
