Problems with my Chrysler 440

"Here's a summary of what's gone on over the past few days. Not sure it all is related but thought it's worth mentioning it all.

- First, the engine ran fine from the beginning of August to a few days ago, thanks to Fast Jeff's suggestion to check the anti-siphon valve. That did the trick and got the gas flowing fine.
- I have two tanks and for the season had been running off the port tank. The starboard tank has old gas in it and in the beginning of the season ran rough so I decided to forget about it till I got my problems fixed. I recently started running off the starboard tank but just at the marina, in an attempt to run the fuel level down gradually.
- I changed the fuel filter the other day
- I went out yesterday and could tell that something was up. The engine just didn't sound right. I anchored for an hour or so, then went to start her again. The battery sounded very weak but when I got enough crank, she turned right over and started up. Again, things didn't sound quite right with the engine. She would be running okay but then sound like she wanted to quit, only to revive herself and go on.
- I started trolling for about an hour at about 600 RPMs. Then she quit. I tried starting her and no luck. On the second try, there was a big puff out of the flame arrester. Then next try- nothing. She wouldn't even turn over. I assumed the battery was dead (for what reason I am not sure- I got it in June and it's been charging with each trip). I had to get towed back in.
- When I got back to the marina, I noticed a little pool of gas sitting on top of the engine. I cleaned it up and I tried turning her over a couple times. I could see little drips coming out of the right arm that controls the butterfly valve in the carb. I figured that the gas had stopped up in the carb and had no where to go and found its way out through the opening for the arm.
- Today, I charged the battery and decided to look in the carb. The float needles were sticky and the resovoirs for gas were a bit dirty so I cleaned out everything best I could and freed up the float needles with Gumout.
- I put the carb back together and tried starting her. The battery charger said that it was 100% charged but she didn't crank nearly what she usually does. I still didn't get a hint of getting her to start (for the past month, it was one turn and she'd start right up) and then I saw the drips of gas again.
- Last point- I checked the oil and noticed that it was well above full. Yesterday morning (before going out), the level was at the full mark. Today, it was well above. The color looked okay (not milky) and it didn't smell funny. It was brownish in color. I have no idea where that additional liquid came from but it has me worried.

Any thoughts on what this all means would be appreciated.

Thanks much.

If the water that was in the b

If the water that was in the bad gas got into the cylinder it could cause that hard turn over (water in the cylinder) Id pull the plugs and turn it over and see if water shoots out then run a compression test while you gottem out put the good gas back to it and forget about that tank and drain it with a drill pump or hand pump
 
"It sounds like your floats st

"It sounds like your floats stuck open, and the carb over filled fuel down into the intake. It can happen. And you suck in enough liquid fuel that it starts to hydraulic lock, making it crank slow.
If the plugs are wet with fuel when this happens, I bet it's stuck floats, from old bad gaz."
 
"Thanks guys. Couple questions

"Thanks guys. Couple questions: 1) Does it sound like the floats are still stuck, even though I thought I cleaned them good when I took the carb apart? 2) I will drain the oil and put new oil in. How quickly does that need to be done? Is it doing any harm right now with the gas in the oil?"
