Niar,
Your symptoms are classic for a partially clogged main jet. This can often be cleared by shutting off the fuel, removing the plug over the main jet, and running a fine needle or piece of wire through the jet. Some folks have an adjustable main jet, and clear these clogs (sometimes) by running the needle in and out.
You're going to spill fuel, so smoking lamp is out. I like to jam small towels in the area under the carb to catch the fuel, then hang them on the lifeline to dry.
Keep in mind that all fuel flow is towards the carb, so guess where all the krap ends up? Personally, I try to keep my tank clean, have a big filter before the electric fuel pump, then a small filter between the pump and the carb. I still get the occasional piece of krap that clogs the main jet or gets into the float valve and causes the carb to overflow. I go so far as to keep a second carb on board, cleaned and ready to go. I have good access and the change doesn't take long.
