1994 Mariner 75hp 2 stroke fuel issues?

[Sismond]

Hi guys,
so 2 days ago took my boat after winter break first time out. She struggled a bit to turn over and fire up, but quite understandable after long time sitting. After a bit got her going and she was running just fine. Took her out, but still a bit hard start, so after an hour trip I used carb cleaner and sprayed some into carbs and used a bit of sea foam in my fuel too. Had her going after for quite a bit to burn everything off and took her out of the water. 2 days later I took her out again and to turn over was really hard, later I found due to oxidized wire (guy who owned before used just a regular copper wires for all electric, but I already rewired the entire boat). So I bought a brand new, marine grade, wire and she turns over like never before. But there it ends.
Can't get her to fire up at all. I used fresh fuel, I've changed fuel filter, spark plugs, took apart fuel pump to clean it up, but simply nothing...
Any suggestions?

an update, I checked my spark plugs and all wiring with voltmeter and it all reads a proper numbers. When I loose carb drain screws, there is fuel coming out, so I'm guessing fuel lines up to here are good.
It is kicking my butt right now

Are you raising the fast idle lever ?----Are you pushing the key in while cranking it over ?

Yes, I am. Like I said, she ran fine few days ago. Than I tried to take her out again and still in a dock she stopped while warming up. Since than I can't get her going again.
