Turning over has nothing to do with the carburetor! Your battery is flat. It will need charging.
If the carb is leaking, it is because the float is set wrong or the float valve needle isn't seating properly.
Engines only need three things to run.
A supply of clean fresh fuel (not sitting a year)
A Spark at the right time.
Compression.
You say you cleaned the carb **in** carb cleaner, as opposed to *with* carb cleaner. Did you strip it down, check the float for holes, clean the jets and needles?
Did you drain the carburetor at the end of the season, or shut off the gas valve and run the carburetor dry? If not, the issue is probably varnish and gum from the evaporated gas plugging up the carburetor. You will have to pull the carb apart and clean it.
Hi Shannon:
Possibles:
- Needle valve has been compromised, possibly held open with grit.
Carefully dismantle and blow out all orifices with compressed air.
- Float level set too high. Review the way the float shutoff mechanism works. Make sure the float moves up and down easily and that it still floats as intended. Double check the lever that moves the needle valve. Make sure it is correctly connected to the needle.

Sounds like you need a valve adjustment, if it is popping thru the carb, the intake valve is open at the wrong time, this can be caused by three things, too much gas, timing is wrong (stretched chain) or valves too tight not allowing valve to close. I would adjust valves first.
The carburetor choke valve might be stuck open or not closing when the engine is cold. The engine needs a richer mixture to start. Too rich a mixture (flooding) can also cause trouble. Turn the fuel valve off to be sure the carb isn't leaking when not in use. If it smokes black on startup, it's flooding. Also check the condition of the spark plugs.
Hi Dennis, Do you know where the gas leaked from?
With out knowing that answer it could be the shut off it's self or a needle and seat in the carb, Or a float that is defective or set incorrectly.
I would say that the incorrect of use of gasket goo instead of the proper gasket has spilled into the bowl after assembly and is blocking the main jet --again
when working on a carby , there is no successful "short cut or lazy action"
