Loosen the glow plug about a quarter turn when you get ready to start it. You can also try heating the engine if you have access to a hair dryer or heat gun.

As for the priming method, it may be hard to see the fuel. I have blue fuel lines and blue fuel so if the light is low it's hard for me to tell if I've got a prime too. The other method of priming the engine involves plugging the exhaust and cranking the engine, which you can't do at the moment.
