Lau-warm star trouble with unround engine run and petrol smell from exhaust!

Hello guys, I’ve been having the problem for a few days that my 850 Bj.96 2.0 with 126hp 10V starts badly with Hand-Lau-Warmen engine. He spins for a long time about 10 sec. until he comes and then runs extremely rough. When it first occurred two days ago he went out three times again! This morning he jumped again and I immediately gave a little gas because I noticed the spit immediately. When I opened the driver’s door he stank from behind extremely to fuel! And after 5 to 6 gas bursts he ran again. I have not ordered anything but distributor, candles, and distributor runners! Hopefully come Monday. Just look under the hood rough and first see nothing striking, Merder damage or defects vacuum hoses. Petrol pump runs as usual. Cold and hot he jumps quite normally. Do you have ideas where I should still check? Or is the way candles, distributor already right? I don’t know how old that is. The last workshop bill we get to the car had been from 2017 and at 207 thousand kilometers. Greetings Christian And happy new year still.
