Hi Scott,
After all your attempts tp start it there could be a lot of oil/fuel mix in the crankcase and then the fuel evaporates leaving a lot of oil in the case to nacker your plugs.
Heat both plugs over a gas flame to burn any excess oil of them and try them again.
Bleeding brakes there are vacuum bleeders and a pressure bleeder used to be available from Gunston.
Part of the problem is the master cylinder being a lot higher than the caliper so the air wants to com up not go down.
If I get a stubborn one I remove the calipers and place them on a table or shelf higher than the master cylinder, put a 5 or 6mm thick piece of wood or flat metal plate between the pads to stop the pistons popping out.
We are all going the breath a big sigh of relief when this thing is up an running
John
