IF excessive fuel has washed all oil from cylinder walls - compression will be too low for proper combustion .. Recommend TESTING compression with gauge - even if it passed the test previously - check it again.
IF compression is low due to fuel wash - adding a tablespoon full of transmission fluid (light oil) to each cylinder will boost compression.
I am assuming the ignition spark is adequate enough(?) .. The reason I’m thinking flooded engine is - that’s what you posted - and - the fact that the engine was running ok before hand.
The spark plugs should have obviously had gas on them when removed.
*Hands-on* help by qualified personnel may be in order.
Good luck with it!
