The easiest way to clear the fuel will be to simply unplug the fuel lines and blow the fuel out - but I have never had to do it this way, I just burn it off.

to get ARO in the carb you pull off the airfilter, or remove the foam from it - then you can drip oil straight into the carb. You know to drip it in the glow plug hole too, right....?

Have you got it to start at all yet?
