Hi and welcome..
fuel? I hope you have it properly mixed, since otherwise you're likely making it worse everytime you try.
If I assume that engine sat for a while.. I'd suggest a 1:20 mix for now,
just to get some additional oil back in.
I think we talk some sort of fuel-pump-carb since those are quite common on engines alike.
And you must check the fuel pump.
easiest by just detaching the fuel tank and instead installing a piece of clear tube to the carb,
going to a small container (jam jar or such) with fuel
so that you can see the fuel flowing in the fuel line.
If you don't you can verify a fuel pump issue by raising the jar above the engine.
so the carb will be gravity fed with fuel...
If the engine's starting now you need to fix the carb's fuel pump
That is if you don't have an external fuel pump on the tank..
In short: we need pics!
So that we know what carb what fuel pump and what else we need to deal with
carb cleaning isn't always a one time process.
sometimes the jets are clogged so badly that it takes three or four attempts to have them clean again.
with an integrated pump, you should remove that first, and then boil the carb in lemon juice.
and after that's done, poke all the small vents with some monofilament fishing line
but frankly, the diaphragm of the pump may has been ruptured

ps compression ratio should be around 12:1 to 13:1 ideally
