It will turn over with the electric starter and let's out a puff or
two of exhaust and then stops.
I tried messing with the carb float screw (as this had been a problem
in the past) but the best I get is it running for about 3 seconds and
then stops.

Could be couple of things. Is the tank valve open to the carb?
Sometimes easy to forget about this. Was the spark plug wet or dry
when you took it out? If dry, it is not getting gas. If wet, could
be weak spark or bad gas. Check for spark by leaving the plug wire on
but leave the plug out of the plug hole and crank over the engine a
few times. May be a little hard to see in bright light so look
closely. Don't leave the plug too close to the plug hole or it may
ignite the gas in the cylinder though. Been there done that. Good
luck.
