Make sure you use premium gasoline with your mix as some people have had problems with some regular grades, 10/10 works but i have yet to get some and run 20/12 car/truck fuel, as for the glow plug adapter you can either buy one http://www.horizonhobby.com/Products...rodID=ZEN23445 or make one out of an old automotive spark plug as shown here on my engine http://www.rcgroups.com/forums/showt...low+conversion
As mentioned above i use a OS type F 4 stroke glow plug and after the engine has started you can remove the glow driver as you would on a normal 2 or 4 stroke glow engine, make sure you check that when the carb is closed all the way the engine will stop, there's no ignition to kill it. Good luck and have fun.
