Ah, thanks for clarifying about the fuel lines! A friend said he has a 17mm flare nut crow's foot. When I borrow that I'll open all the lines, crank to purge the existing fuel out til I get air, then supply the fuel from my little bottle and crank again til I get fuel leaking out.
But first I'll try the starting fluid, I'm just waiting to have a helper!
The battery was good, but I've done so much cranking and recharging, I've noticed it runs out a little bit sooner now. But it's still strong enough to allow healthy cranking at least a few times. Also, when I crank, I have jumper cables attached to a second battery (which I also recharge). I wish I had one of those big 200 amp battery chargers / car starters.
I have no block heater.
I never ran VO, WVO or bio.
