You wouldn't be the first person to be caught out by duff petrol. The stuff they make these days doesn't have a very long shelf life. If the fuel is new then that is not the problem. Given good fuel, compression and a healthy spark at the right time, it should at least attempt to fire. Can you be sure that there is not any water getting into the bores? If a plug looks wet it will be either oil, petrol or water.
I would also change the condenser. That's where I would start anyway.
