I wanna ride, HELP please please

So I just recently bought an '86 750, it has 27,000km on it and looks good. Thats where the good stops, lol. My problem is the front (and possibly rear to a lesser extent) cylinder is flooding and I mean like completely full with gas. I bought it not running because of a bad stator.

Here's a run down on what I've done:
Replaced the stator with a high output one
Replaced the plugs
Oil/filter
Pulled the carbs and sprayed carb cleaner in everywhere, never actually removed the floats or jets
With the carbs pulled and blowing in the fuel lines, then rotating the carbs the float needles appear to seat as I can't blow air through.
Pulled the plugs and cranked it over to expel the gas and then started her up and went for a spin around the block, it seems to pull "choppy" with power then lack of then picks up again. Turned the petcock to prime and seems a little better but after parking for ten min or so (petcock still on prime) I get gas leaking from all around/over the carbs. And with the petcock left on run the cylinder will be full of gas after maybe 30 min.
Pulled the vacuum line off the petcock and it "closes" when you suck on it. (Damn I suck/blow on any other part of this and I'm have to start makin it pay $$)
When it first happened (cylinder full of gas) it started for a min, leaked gas out of the surge tank, and then died. The oil was loaded with gas and was promptly changed.
Idles low now, havent messed with the idle screw.
Sometimes will hold at 3-4k when throttle closed.
Will sometimes idle low and start dipping then stall.
Seems to run good around 5-7k.
Can be fussy when trying to start.

I'm at a loss, advice or info is GREATLY appreciated.

Thanks in advance, Mak

Pull the carbs again and open up the float bowls. You'll want to pull the pin out of the floats and pull each float and needle. Inspect the needles for crud. Then blow Gumout (or any carb cleaner) into the seat for the needle, and make sure to blow it dry with compressed air. Do this until you're certain those float bowls are clean; reassemble, reinstall, and you should be good to go.

Cool, will do asap. I hope thats my problem and I'll update when it's done.
Thanks for reading through my rambling my patience is dwindling, it's so frustrating when it's nice and the bike is just sitting.

Thanks again, Mak

I don't kinow which part of the country your in but Here in North California we have a bug here My Dad calls a Leaf-Roller.
The bike I got wasn't setting more than a month or month and a half.
Well the Vacuum lines going to the carbs were loaded with Rolled-Leafs.
So if your's has been sitting for a while you might want to blow out all the lines that
something could get into.............

And once your carbs are clean, you may still get a stuck float. Someone else posted that a while back, and I shared my MacGyver fix when it happened to me. After spending a good chunk of change on a new coil, not to mention re-cleaning the carbs repeatedly, I was at a loss. Finally I gave a good rap on the float bowl with a tool (forget what now, probably a screwdriver handle). Knock on wood it worked. Even clean floats get stuck sometimes, although not often.

Cool, I'll keep it mind. I just kinda half assed it last time I cleaned them, tryin to rush and get her on the road. Planning on gettin her done tomorrow night I'll let ya know how it goes. Do you guys think all the problems are related to the floats? I'll make sure I get everywhere in the carbs for now, I'm planning on the ear shave and gb removal. Anyone know where to get the jets online? I having a hell of a time finding a site that has 'em or at least one that I can manage to navigate on, so many crappy little sites that are a pain to find stuff on. Anyhow, wish me luck on fixing the beast.
Thanks again, Mak
