Sputtering through the carb is an indication of a stuck valve to me.

Did you get the mag put back on exactly like it was? Could be a little out of time.

One of two things. Either you still have a stuck valve, or the Mag timing is off a tick.

mag timing, carb is trying to flood (check AND clean your plugs), Fuel.... If you are using an ethanol based fuel, get rid of it. I only use Non-Ethanol in my tractors as the ethanol is Hydroscopic (google it) and will add moisture to your tank which turns into water.

Funny my WC sat all winter with E10 in it and fired off on the 4th pull of the hand crank. Did the same thing the last several winters. Check the sediment bowl. If no water there, that's not the problem.
