Question Fuel system flooding

I purchased a 72 350sl with a 4,5l V8 about a month ago. It had been sitting for about 2 years so I drained the gas tank, flushed the lines with new gas and drain again, then installed a new fuel filter, added new gas with treatment. I started the engine, it ran good for about 30 seconds then started running rough and putting out black smoke. I shut it off and could not get it started again until I remove the spark plugs and dried out the cylinders and plugs, which were soaked with gas. What would be the things I need to check and or replace? I cant afford to spend much because money is very tight.
