747 I use a spray bottle the kind you get at the hardware store or that comes with cleaners like 409 they give a good spray jet.
if I get dirt in my carb or needle area I will hold the engine upside down so the alcohol runs out when clean,or dirt free I will oil it with 3in 1 oil or air tool oil to prevent corosion a few drops is all it takes,if you don't have any WD-40 will be OK for a temp lube to resist moisture.for long term storage a good after run oil is recomended.
